1.1 Key Highlights for MSC.Patran 2005MSC.Patran 2005 introduces a series of key features that streamline the process and expand the scope of simulation modeling. The highlighted new features for 2005 focus on further analysis integration by supporting many additional capabilities of MSC.Nastran, MSC.Marc, MSC.Dytran, ABAQUS, and other codes. These new features are aimed at making the modeling-analysis process more inclusive and seamless. Some of the key features in MSC.Patran 2005 are:

Scalar Marker PlotsA scalar marker plot tool has been added to MSC.Patran 2005. In addition to producing vector and tensor marker plots, you can now generate scalar marker plots that use nodal or element based scalar data.

The Scalar Marker plot capability is accessed from the Result Application form by setting the Action>Object>Method to Create>Marker>Scalar. Scalar plots may be colored and scaled based on value and may be targeted at various model features such as node, faces and edges of elements, and corners.

For more information on this feature please see Marker Plots (Ch. 6) in the MSC.Patran Reference Manual, Part 6: Results Postprocessing.

MSC.Nastran Preference Enhancements

MSC.Nastran Explicit Nonlinear (SOL 700) Support

MSC.Nastran version 2005 introduced a new Explicit Nonlinear analysis pre-release capability that complements and extends the existing nonlinear capabilities available with SOL 106, SOL 129, and SOL 600. SOL 700 provides numerical methods and techniques for large displacement analysis of structures, with a wide range of nonlinear material models, and contact modeling of deformable and rigid bodies.

MSC.Patran version 2005 was developed in close coordination with MSC.Nastran 2005 aimed at offering you immediate interfacing to SOL 700. Because of the extensive nature of this implementation, the new SOL 700 support is a pre-release capability for 2005. For details on new interface capabilities for SOL 700, see Explicit Nonlinear SOL 700 Support (Pre-release) (Ch. 3).

Double Precision Support

This enhancement of MSC.Patran is to support double precision for all FEM related data where the accuracy of MSC.Nastran results are highly dependent.

In previous releases all the values of FEM data were represented by single precision in the MSC.Patran database. This enhancement updates MSC.Patran to support double precision in these areas:

Page 7: · PDF fileCONTENTS MSC.Patran Release Guide 1 MSC.Patran 2005 ... INDEX MSC.Patran Release Guide, 113. MSC.Patran Release Guide CHAPTER1 MSC.Patran 2005 at a Glance Key Highlights

3CHAPTER 1MSC.Patran 2005 at a Glance

• Grid coordinates

• MPC coefficients

• Coord coefficient

In the multiple processes of simply importing and exporting FEM related data to and from MSC.Patran during a typical product lift cycle, it is required that MSC.Patran retain all the original numbers of significant digits for the preceding FEM related data.

Rigid Element Support

In MSC.Nastran 2004, a new Lagrange Rigid Element was introduced. MSC.Patran supports the new Lagrange rigid element type, as well as new rigid element bulk data entries that were added in MSC.Nastran 2004.

• Added support for the RIGID case control command via the solution parameters form for solution types 101, 103, 105, 106, 129, and ultimately 400.

• Added support for the Thermal Expansion Coefficient value in the RBAR, RBE1, RBE2, RBE3, RROD, and RTRPLT rigid elements.

• Added support for the new RBAR1, RTRPLT1, and RJOINT rigid elements, the first two of which also include the new Thermal Expansion Coefficient constant.

• Updates to the MSC.Nastran preference MPC definitions, adding the Thermal Expansion Coefficient to applicable existing MPC definitions, and adding new definitions for the RBAR1, RTRPLT1, and RJOINT rigid elements.

• Updates to the Analysis Solution Parameters form to allow the rigid element type to be specified (LINEAR, LAGR, or LGELIM). Additionally, the job control output was updated to include a RIGID_ELEMENT_TYPE parameter that may have one of these three values.

For more information about rigid element support please see, Multi-point Constraints (p. 23) in the MSC.Patran MSC.Nastran Preference Guide, Volume 1: Structural Analysis.

Direct Results Access

Direct Results Access now supports MSC.Nastran solutions 103, 105, 106, 107, 108, 109, 110, 111, 112, 129 and 200

Multipoint Constraint Numbering

Multipoint constraint numbering has been changed in MSC.Patran so that the MPCs you create will have the same ID as they will have in the MSC.Nastran input deck. Also, you will be warned if an attempt is made to renumber the MPCs or elements when translated to the MSC.Nastran Input deck.

Preserve MSC.Nastran Names

A feature has been added that reads and uses the material and element properties names from the MSC.Nastran Bulk Data File when importing the BDF into MSC.Patran. For more information about preserving the MSC.Nastran names, please see Entity Selection Form (p. 410) in the MSC.Patran MSC.Nastran Preference Guide, Volume 1: Structural Analysis.

External Superelements

External Superelements in MSC.Nastran are now supported in MSC.Patran. For more information please see, External Superelement Specifications (p. 204) in the MSC.Patran MSC.Nastran Preference Guide, Volume 1: Structural Analysis.

Connector Element Support

The Connector Element project has added support for connection elements in MSC.Patran. It specifically targets the generation, translation, and results processing of MSC.Nastran Spot Weld (CWELD) and fastener (CFAST) connectors within MSC.Patran. Please see Creating Connectors (p. 122) in the MSC.Patran Reference Manual, Part 3: Finite Element Modeling.

Support for Global Ply Tracking (PCOMPG)

MSC.Nastran 2004 introduced Global Ply Tracking for composite material analysis. This feature makes it possible to track stresses in individual plies, where there may be ply drop-offs or reversed elements, using the conventional zone description of the layup. The global plies in the composites layup are assigned a global ply ID(GPLYID) that is specified for each layer of a given laminate material. These global ply IDs are input using the PCOMPG bulk data entry. Following an analysis, MSC.Nastran sorts the ply results in the .op2 and .xdb files by global ply ID and enables easy interpretation of results.

MSC.Patran 2005 fully supports the manual generation of PCOMPG input data so that you can benefit from the MSC.Nastran capabilities from within a graphical interface environment. Global Ply Tracking when used with MSC Laminate Modeler provide automatic sorting of results in the analysis code, correct ply orientation of vector and tensor marker plots, and a standard archiving of ply models within MSC.Patran database and MSC.Nastran input file. For more information please see, Support for MSC.Nastran PCOMPG (p. 43).

5CHAPTER 1MSC.Patran 2005 at a Glance

MSC.Marc Preference EnhancementsMSC.Patran 2005 includes numerous enhancements specific to the MSC.Marc Preference and expanded support for a number of MSC/Marc capabilities.

Results Postprocessing Improvements

Animation (Quick Plot) improvements allow you to quickly animate multiple result cases and create MPEG movie clips from within the Quick Plot action. This is especially useful for processing nonlinear incremental data.

In addition access speed to the MSC.Marc results (POST) file has been upgraded.

Multipoint Constraint Enhancements

Full implementation of MSC.Nastran style RBE3 elements is complete and can be accessed under the FEM application for MPC creation.

A new Tying 69 multipoint constraint has been added to this release for use in bolt or rivet pre-tensioning applications. Tying 85, 86, and 87 for heat transfer analysis are also available. These MPCs enable you to tie together temperature degrees of freedom.

Material Models

Version 2005 now supports virtually all MSC.Marc material models including accessibility to activate material subroutines. Tables are supported for all material properties that reference fields.

Loads and Boundary Conditions

Enhancements have been made to the 1D Pressure and CID Distributed Loads capabilities. Tables are also supported for all load and boundary conditions that reference fields.

Contact

Improvements for controlling individual contact pairs and support for defining a rigid heat transfer body are new to 2005. In addition, contact properties and motion defined by fields can now be written as tables.

Table Support

Variations of material properties, load values, and other parameters are now definable in MSC.Marc 2005 via the TABLE parameter and option entries. The MSC.Marc Preference supports the new TABLE entry by converting referenced fields in the Materials and Loads/BCs applications directly to this table format.

Domain Decomposition

Domain decomposition can now be done automatically as part of the analysis process.

Output Requests

The output request forms can now process numerous new element results and nodal results POST codes.

User Subroutines

New user subroutines can be activated via the MSC.Marc preference.

For details on MSC.Marc Preference updates, see MSC.Marc Preference Enhancements (Ch. 3).

MSC.Dytran Preference EnhancementThe ACC Output Request, IMMFILE file management and several parameters were added to the Analysis form of the MSC.Dytran Preference in MSC.Patran 2005. For details on MSC.Dytran Preference updates, see MSC.Dytran Preference Enhancements (Ch. 3).

ABAQUS Preference EnhancementABAQUS Gasket Element Support has been improved in MSC.Patran 2005. The link, axisymmetric, two, and three-dimensional gasket element types were added to the Element Properties of the ABAQUS Analysis Preference in MSC.Patran 2005. Damage and Elastic-Plastic gasket behavior models that vary with displacement and temperature may be assigned to these property sets. Traditional elastic, plastic, viscoelastic and creep material models may also be used. The thickness direction is defined from the gasket element's connectivity. A shareware utility was created to allow the connectivity of Hex elements to be easily rotated. For more information on ABAQUS Preference updates, see ABAQUS Product Information (Ch. 1) in the MSC.Patran ABAQUS Preference Guide.

You can now automatically create MSC.Patran Groups from Layers during the file import process. This feature is supported for all CAD Access products and you have the option of specifying a group name or reverting to a default naming convention.

Export

MSC.Patran 2005 has expanded its export capability to enable you to export to the following formats:

• CATIA V4

• I-DEAS

• ACIS

• VDA

• STEP 214

Results Improvements

Results Title Editor

This release of MSC.Patran further expands the postprocessing capabilities with a new Results Title Editor.

Previously, you needed to individually edit a title on each Results Tool Attributes form. For 2005, a separate form is available and accessed from the Attributes forms. The new form provides a user-friendly interface for accessing all of the internal information available for results titles and adding any additional text you might desire. Complete documentation of the new form, can be found in Results Title Editor (Ch. 1) in the MSC.Patran Reference Manual, Part 6: Results Postprocessing.

9CHAPTER 1MSC.Patran 2005 at a Glance

Results Type Naming Consolidation

Results labeling within MSC.Patran was inconsistent with regard to the source of those results in XDB, DBALL or OP2 files. In MSC.Patran 2005, the functional results labeling in MSC.Patran from all MSC.Nastran sources has been consolidated. For example prior to 2005 release, CBEAM combined stresses were stored under the results label “Bar Stresses, Bending”. This is incorrect since the combined CBEAM stresses include both bending and axial components. When CBAR and CBEAM are used in the same model, two different results types are displayed with the same label.

In MSC.Patran 2005, the following CBEAM results have been renamed:

• Bar Stresses, Bending => Beam Stresses, Combined

• Bar Stresses, Maximum Combined => Beam Stresses, Maximum Combined

• Bar Stresses, Minimum Combined => Beam Stresses, Minimum Combined

• Bar Stresses, Tension Safety Margin => Beam Stresses, Tension Safety Margin

• Bar Stresses, Compression Safety Margin => Beam Stresses, Compression Safety Margin

• Bar Forces, Translational => Beam Forces, Translational

• Bar Forces, Rotational => Beam Forces, Rotational

• Bar Forces, Warping Torque => Beam Forces, Warping Torque

• Bar Strains, Maximum Combined => Beam Strains, Maximum Combined

• Bar Strains, Minimum Combined => Beam Strains, Minimum Combined

• Bar Strains, Tension Safety Margin => Beam Strains, Tension Safety Margin

• Bar Strains, Compression Safety Margin => Beam Strains, Compression Safety Margin

2.3 CAD ExportsThe File>Export capability has been updated by adding the following CAD formats available during the file export process:

CATIA V4

Selecting a CATIA V4 export generates a .model file compliant with CATIA version 4.1.9. The export translator does not interact with CATIA or the CATIA API and does not require a CATIA installation. Any number of curves, surfaces, or solid may be exported.

I-DEAS

The I-DEAS export translator creates a I-DEAS MS9 .mf1 file. The export translator does not interact with I-DEAS Master Modeler and therefore, does not require an I-DEAS MS9 installation. Any number of curves, surfaces, or solid may be exported.

ACIS

When exporting using the ACIS source, a ACIS save (SAT) file is generated compliant with ACIS version 13.0. Options are provided for exporting selected curves, surfaces, and solids. Scaling is automatically performed to convert from millimeters (ACIS) to meters (Parasolid) units.

VDA

Selecting to export to VDA generates a .vda file that is compliant with VDA version 2.0. Options are provided for exporting any number of selected curves, surfaces, and solids.

STEP 214

The previous version of MSC.Patran exported to STEP 203 and 209 formats. Version 2005 adds an export for STEP 214 format that creates a STEP AP214 (.st) output file. Any number of curves, surfaces, or solid may be exported as Class II or Class IV entities.

3.1 MSC.Nastran Preference EnhancementsMSC.Patran 2005 represents our ongoing commitment to provide unique end-to-end simulation modeling tools to facilitate the enterprise-wide virtual product development process. The primary focus of the MSC.Nastran Preference enhancements for this release was to streamline the engineering process though discipline integration. Here are some of the key feature enhancements for this release:

Explicit Nonlinear SOL 700 Support (Pre-release)Support for SOL 700 is a pre-release capability for 2005. It is being presented for your feedback on usability and suggestions on the implementation, which will help migrate this to full release status in subsequent MSC.Patran releases.

SOL 700 is the explicit nonlinear solver of MSC.Nastran which uses the MSC.Dytran LS-Dyna module as its solver engine. MSC.Dytran LS-Dyna is a 3D explicit nonlinear analysis code with DMP (Distributed Memory Parallel). The solver, currently limited to the structural analysis, can be used for automotive crash, wheel impact, droptest and component crush.

Explicit Nonlinear SOL 700 is accessed from the Preferences menu of MSC.Patran as shown in the following picture:

43CHAPTER 3Analysis Preferences

Support for MSC.Nastran PCOMPGComposite materials are used increasingly for complex primary aerospace structures. A fundamental requirement of composites analysis is to produce accurate models of the complex structure and recover meaningful results data. Where the ply layup incorporates ply drop-offs or reversed elements, it is difficult or impossible to track stresses in individual plies using the conventional zone description of the layup. This increases the cost of certification and makes it difficult to understand the contribution of individual plies in order to improve the design. As a result, global ply tracking was incorporated in MSC.Nastran 2004.

Using this method, the global plies in the composites layup are assigned a global ply ID(GPLYID) that is specified for each layer of a given laminate material. These global ply IDs are input using the PCOMPG bulk data entry, which is otherwise identical to the existing PCOMP entry used to specify laminate materials. The GPLYIDs must be positive and unique within each PCOMPG entry. After solution, MSC.Nastran will sort the ply results in the .op2 and .xdb files by global ply ID to enable easy interpretation of results. Printed results can be written to the .f06 file if the GPRSORT parameter is specified. The relationship between local layer indices and global ply IDs for a typical layup are shown below.

MSC.Patran 2005 contains complete support for the manual generation of PCOMPG input data. This allows ready use of the new MSC.Nastran capabilities from within a useful graphical environment. Furthermore, global ply models can now be generated extremely efficiently using the MSC.Patran Laminate Modeler, allowing the use of global ply tracking in complex components and structures.

Ply Modeling Requirements

During the composites development process, the details of the composites layup are not considered during initial sizing and so a conventional zone-based composites description is typically used. In fact, for preliminary work the layup on a property region is often smeared (using MSC.Nastran’s SMEAR and SMCORE options) as an aid to rapid design improvement. However, as the design evolves, the ply details must be specified in order to ensure a producible part as shown below.

For the certification of aircraft structures, it is important to understate the detailed stress state of each global ply. For effective visualization, it is important that results are plotted on the basis of global plies. The need for this is clearly illustrated with a simple model of crossing plies shown below. Using a conventional zone description of the layup, the results are difficult to visualize as they do not reflect the arrangement of the structure. Even worse, results from plies that may be of different material, thickness, and orientation are shown together and perhaps interpolated. By contrast, the global ply model allows you to interpret the model effectively. Furthermore, detailed stresses on a ply basis are optionally available in the f06 file for the purposes of certification.

45CHAPTER 3Analysis Preferences

Manual Creation of PCOMPG Data

MSC.Patran 2005 enables you to create global ply models using its productive and familiar interface. Within the material application, the spreadsheet for defining laminate layer data simply incorporates an additional column where global ply IDs can be defined. Note that it remains possible to define no global ply IDs, which would result in a conventional PCOMP card being generated. If global ply IDs are needed, each layer must have a positive GPLYID that is unique in that laminate material. In order to clearly differentiate between layered and global ply results, it is recommended that GPLYIDs be chosen from a range that will not overlap with layer indices. For example, for typical models that have fewer than several hundred layers, it is good practice to number ply IDs beginning at 1001.

46

When writing out the MSC.Nastran input deck, you must specifically request the writing of global ply IDs on the translation parameters form as shown below. This is ON by default. It is also possible to set the GPRSORT parameter in the Case Control Section using direct text input.

Following the analysis, simply access results in xdb or op2 format and select the appropriate global ply ID as shown below. Note that vector or tensor marker plots of sorted global ply results are oriented correctly as MSC.Patran obtains the correct orientation using the global ply ID. If the global ply IDs overlap the layer indices, a warning will be issued to highlight the orientation ambiguity.

47CHAPTER 3Analysis Preferences

Automated Modeling of Global Plies

The full power of the new global ply modeling capabilities are best shown through the use of the MSC.Patran Laminate Modeler. This tool has allowed advanced users to model on the basis of plies for the past decade. The main advantages of ply modeling are the ability to generate and modify composite analysis models rapidly, and the incorporation of realistic orientation data in the model.

For example, consider a surface with three property regions resulting from a simple ply layup in the model below. If subsequent analysis shows that the structure needs reinforcement, you have to define six property regions manually. So, for realistic models of any complexity, it is essential to use the ply modeling capabilities of the MSC.Laminate Modeler.

Page 52: · PDF fileCONTENTS MSC.Patran Release Guide 1 MSC.Patran 2005 ... INDEX MSC.Patran Release Guide, 113. MSC.Patran Release Guide CHAPTER1 MSC.Patran 2005 at a Glance Key Highlights

48

Because MSC.Laminate Modeler established the concept of global ply modeling, the basic tools are already in place and so it is easy to generate an accurate model. Simply create Materials and Plies as usual, then optionally specify a global ply ID associated with a ply instance in the Layup spreadsheet. You have the option of specifying no GPLYIDs, creating sequential GPLYIDS beginning from a particular value, or manually defining GPLYID for full control. By default, sequential ply IDs beginning at 1001 are used.

Page 53: · PDF fileCONTENTS MSC.Patran Release Guide 1 MSC.Patran 2005 ... INDEX MSC.Patran Release Guide, 113. MSC.Patran Release Guide CHAPTER1 MSC.Patran 2005 at a Glance Key Highlights

49CHAPTER 3Analysis Preferences

Once the global ply ids are specified, simply create the composite analysis model as usual to generate the PCOMPG data.

As can be seen in the figure below, the new PCOMPG capabilities extend and enhance the capabilities of the MSC.Laminate Modeler in a number of important respects. With PCOMPG, ply results are sorted automatically by the analysis code, so that this sorting does not require a discrete process within MSC.Patran. Vector and tensor plots of sorted plies have correct orientation, which was impossible before. Most importantly, the MSC.Patran database and MSC.Nastran input deck contain a global ply model, easing the problems of archiving ply models and allowing organizations to implement global ply modeling as the standard technique for accurate composites modeling.

3.2 MSC.Marc Preference EnhancementsNumerous enhancements have been made to the Marc Preference for 2005.

Results Postprocessing ImprovementsThe following postprocessing improvements have been implemented:

• Animation (Quick Plot) Improvements

The Results’ application Quick Plot capability has been improved to better suit processing of nonlinear incremental results. This enhancement is not necessarily particular to the MSC.Marc Preference, but will be especially appreciated by those that must process incremental data. It is now possible to quickly animate multiple result cases and create MPEG movie clips from within the Quick Plot action. Specific to the MSC.Marc Preference is that this works with adaptive mesh results.

1. Quick Plot action.

2. Select multiple result cases and the result to plot.

3. Turn ON Animation.

4. Set mode to Animation Options.

5. Set MPEG file generation or other settings.

6. Press Apply.

51CHAPTER 3Analysis Preferences

• Result Access Improvements

In addition to the animation improvements, access speed to the MSC.Marc results (POST) file has been significantly sped up. This is most notable when accessing element nodal data such as stress or strain tensors whose results reside at integration points or nodes. This speeds up static plots and animations over the previous release by an order of magnitude in some extreme cases.

Multipoint Constraint Enhancements (MPCs)Available under the FEM application (Finite Elements) for MPC creation, the following multipoint constraints have been enhanced or added:

• RBE2/RBE3

Although available in the last release, full implementation of MSC.Nastran style RBE3 elements is now complete. To take advantage of large rotation RBE3 formulations, you must use MSC.Marc 2005. RBE3 constraints define motion at a referenced node as the weighted average of the motion at a set of other nodes.

One reference node (tied or dependent term) with degrees of freedom (dof) and an unlimited number of other nodes (retained or independent terms) with dofs are defined. The total number of dofs of the tied node and retained nodes must be the same, although they may be distributed among the different retained nodes. The retained nodes can be broken up into sets with different weighting factors applied to them. In addition to the one reference node, additional dependent terms can be defined consisting of a subset of the retained or independent terms, which define the “UM” set as the tied nodes. This allows the reference node’s dofs not to be eliminated from the system matrices. This is optional and by default the reference node’s dofs are eliminated unless additional dependent terms are defined.

Keep in mind that two dimensional problems such as plane strain/stress and axisymmetric problems use only the UX,UY, and RZ dofs whereas three dimensional problems use all six dofs.

Weighted, retained nodes and dofs. Same dof set defined here must be defined in reference node, although they may be distributed to the different retained nodes.

Additional tied nodes. These are optional. But, if used, they must be a subset of the retained nodes.

53CHAPTER 3Analysis Preferences

• TYING 69

This multipoint constraint is new to MSC.Marc 2005 and, in general, is used for bolt or rivet pre-tensioning. This tying type is called an Overclosure, signifying that you can create a general section constraint between two parts of a model to define a gap or overlap. A gap will create a compressive pre-stress in the two parts whereas an overlap will create a tensile pre-stress.

Each overclosure is defined by selecting all the nodes on one side of the section as the dependent (or tied) nodes; these are the dependent terms. The corresponding nodes on the other side of the section are the independent terms or retained nodes. However each independent term must have two retained nodes, the first being the corresponding node on the other side of the section and the second being a reference node. The reference node must be the same for all independent terms and is the node on which a force or displacement constraint is placed in order to cause the gap or overlap and thus the tension or compression pre-stress.

Independent terms or retained nodes. Each independent term consists of two nodes, the last being a reference node. The reference node must be the same for all independent terms. The first node is the node on the other side of the section corresponding to its dependent term.

57CHAPTER 3Analysis Preferences

• Viscoelastic Model (SHIFT FUNCTION)

The shift function parameter for viscoelastic material groups that exhibit thermo-rheologically simple behavior is now available for the following models: Williams-Landel-Ferry, Power Series, Narayanaswamy, and User Subroutine.

• Latent Heats (TEMPERATURE EFFECTS)

For thermal and coupled analysis, the latent heat versus solidus and liquidus temperatures can be defined via fields.

• Damage Models (DAMAGE)

The Gurson model for elasto-plastic materials, and the elastomeric model for elastomeric models, as well as a simplified damage model are all now available.

• Concrete Cracking (CRACK DATA)

Material properties for concrete cracking including user subroutine.

• Forming Limit Diagram (FORMING LIMIT)

This option defines the variation of forming limit properties with minor principal engineering strain. Three methods for describing the forming limit diagram curves are supported: fitted, predicted, and via a table.

• Grain Size Growth (GRAIN SIZE)

Grain size growth model allows you to predict the grain size based on the process history. The grain size can be placed on the POST file for viewing.

• Soil Material Model (SOIL)

Although full control for soil analysis is not yet fully supported, as a prelude, the soil material model has been added including INITIAL POROSITY, INITIAL VOID RATIO, INITIAL PC, and SPECIFIC WEIGHT as well as control via user subroutine.

• Powder Material Model (POWDER)

The powder model is now available including user subroutine access. Initial relative density (RELATIVE DENSITY) is also definable. Properties that vary with density (DENSITY EFFECTS) can be defined although this capability is still limited.

• Elastic-Plastic Hardening (ISOTROPIC, WORK HARD)

The Kumar and Chaboche hardening rules are now available. Also plastic strain hardening data can be entered as either true stress vs. natural log of plastic strain or as engineering stress/strain. If the first (stress, strain) data pair in the defined field has zero plastic strain, then true stress/strain is

Page 62: · PDF fileCONTENTS MSC.Patran Release Guide 1 MSC.Patran 2005 ... INDEX MSC.Patran Release Guide, 113. MSC.Patran Release Guide CHAPTER1 MSC.Patran 2005 at a Glance Key Highlights

58

assumed with the first stress value being the yield stress. If the first data pair has non-zero values for both stress and strain, then engineering stress/strain is assumed and converted to true stress/strain on creation of the MSC.Marc input deck.

• Elastic-Plastic Yield (ISOTROPIC, ORTHOTROPIC, ANISOTROPIC)

The Hill and Barlat yield criteria are now available.

• Table Support (TABLE)

All material properties for any constitutive model that references a field will be written as a table to the MSC.Marc input deck if this capability (new to MSC.Marc 2005) has been turned on. Capability to write tables is accessed under the Job Parameters form in the Analysis application. See Table Support (p. 62).

Loads and Boundary ConditionsThe following enhancements have been made to the Loads/BCs applications:

• 1D Pressures

Support for pressures on 1D elements has been added. These elements must be defined as either Planar Beams or Axisymmetric Shells under the Element Properties application before the pressures can be applied. Below is an illustration of an external pressure applied to a spherical shell modelled with 1D axisymmetric shell elements.

• CID Distributed Loads

Page 63: · PDF fileCONTENTS MSC.Patran Release Guide 1 MSC.Patran 2005 ... INDEX MSC.Patran Release Guide, 113. MSC.Patran Release Guide CHAPTER1 MSC.Patran 2005 at a Glance Key Highlights

59CHAPTER 3Analysis Preferences

The capability to apply directional, distributed loads to element edges or faces has been expanded and is also a new feature of MSC.Marc 2005 for some elements. In two dimensional analysis involving plane stress/strain or axisymmetry, elements can now be given a directional pressure (or line load) on the element edges.

For three dimensional analysis, you load faces, not edges. This is valid for Membranes, Thick Shell, and Thin Shells. All 2-D element types will support either a face load or an edge load, but not both. This is dependent on whether the analysis is two or three dimensional. Below shows a 2D solid and a shell implementation:

This capability is also applicable to three dimensional beam elements. In all cases the appropriate load type is assigned to the DIST LOADS option in the MSC.Marc input deck.

Current limitations for this include no support for local coordinate frames (everything has to be set up in the global frame), and no support for 3D Solid elements.

• Table Support (TABLE)

All loads and boundary conditions that reference fields to define time and/or spatial variations will be written as tables to the MSC.Marc input deck if this capability (new to MSC.Marc 2005) has been turned on. Capability to write tables is accessed under the Job Parameters form in the Analysis application. See Table Support (p. 62).

ContactThe following improvements have been made to contact in the MSC.Marc Preference:

• Better Control of Individual Contact Pairs

The Contact Table form now allows all body pairs to be given separate property values as required. Select the body pair from the Touching and Touched list boxes as shown below. You may then set all the shown properties in the frame. New to this form are the Contact Detection, and Stress Free Initial Contact, among others, for both Structural and Thermal properties.

• Rigid Heat Transfer Body

In the Loads/BCs application and for coupled analysis, the ability to define a deformable body as simply a rigid body but with thermal heat transfer capability is now possible. Of course, when this is done, the body is no longer considered a deformable body, but simply a rigid heat transfer body.

• Table Support (TABLE)

All contact properties and motion that can vary with time or some other independent variable defined by Patran fields will be written as tables to the MSC.Marc input deck if this capability (new to MSC.Marc 2005) has been turned on. Capability to write tables is accessed under the Job Parameters form in the Analysis application. See below.

Table SupportVariations of material properties, load values, and other parameters are now definable in MSC.Marc 2005 via the TABLE parameter and option entries. The MSC.Marc Preference supports the new TABLE entry by converting referenced fields in the Materials and Loads/BCs applications directly to this table format.

For loads and boundary conditions (including contact), when the new TABLE entry is used, all are written to the Model Definition section of the input deck. A LOAD CASE entry is used to call out the various loads applicable during any particular load case within the MSC.Marc input deck as defined in the History section.

This new functionality is accessible under the Job Parameters form in the Analysis application. You must turn ON, the Use Tables toggle in order for the TABLE and LOAD CASE options to be written. You have control of whether these options are written for Materials, Loads, or Contact as shown below.

63CHAPTER 3Analysis Preferences

Domain DecompositionDomain decomposition methods in MSC.Marc have been extended to be done automatically as part of the analysis process.

There are now three methods of defining domains in the MSC.Marc Preference for parallel job submittal. In addition to the Manual method where domains are defined as Patran groups and the Semi-Automatic method where a Metis algorithm automatically creates Patran groups as the defined domains, you can set the Decomposition Method to Automatic. When this is done, no Patran groups are necessary and a single input file is created and submitted to MSC.Marc unlike the other methods where multiple files are generated for each domain. MSC.Marc uses its built-in domain decomposition algorithm to automatically split the model into the necessary domains for the job to run in parallel mode.

Domain decomposition is accessed under the Analysis application when the Object is set to Domains.

Output RequestAdditional POST codes can now be requested via the Output Requests forms. Additions or modifications in this release for element results include:

4.1 Loads/BCs Display Behavior

OverviewIn MSC.Patran 2005, the method by which LBCs are displayed has been enhanced to improve the memory management in the display process. For a model with loads applied to 300,000 elements, memory usage is now reduced by 500 MB.

In previous releases of MSC.Patran, LBC display performance could be slow depending on the model size. For large models, the time to create an LBC on a large number of entities is usually dominated by the creation and rendering of the display data.

Some LBC display behaviors have also been altered so only the requested LBCs will be plotted.

Example:

• 4 LBCs are in the current Loadcase

• Only 1 LBC is plotted

• Delete the plotted LBC

In previous releases, MSC.Patran would re-plot the 3 remaining LBCS. In MSC.Patran 2005 the remaining LBCs will not reappear.

In MSC.Patran 2005 nothing is re-plotted.

Page 83: · PDF fileCONTENTS MSC.Patran Release Guide 1 MSC.Patran 2005 ... INDEX MSC.Patran Release Guide, 113. MSC.Patran Release Guide CHAPTER1 MSC.Patran 2005 at a Glance Key Highlights

79CHAPTER 4Updates to Basic Functions

Other LBC Display Behaviors ChangesTo further improve LBC display processing times LBC marker data is not created if Display/Load/BC/Elem.Props… Show LBC/El. Prop Vectors toggle is off.

In previous releases, MSC.Patran always created marker data for an LBC when the LBC was created, even if the vector toggle was off and the markers did not display.

In MSC.Patran 2005, if the toggle is off, no marker data is created or displayed. A warning message is given, and you can use LoadsBCs/Plot Markers to display markers at your discretion. For large models, this can greatly speed up the Loads/BCs creation process.

• Show LBC/EL. Prop. Vector OFF

• Apply Pressure to model

Display Cleanup

The functionality of the broom (display_cleanup() command) icon located on the Main form toolbar has been enhanced. In previous releases of MSC.Patran the broom removed LBC markers from display, but it left marker data on the database that was no longer being used.

In MSC.Patran 2005, the broom erases the memory of what LBCs were plotted. In the previous scenario, only the new LBC would be plotted when created. Any set of LBCs may still be plotted from LoadsBCs/Plot Markers.

The use of the broom before closing a database will result in a smaller database depending on the number of LBCs displayed.

You may notice a longer delay when using the broom if many LBC markers are displayed. However, this time is recovered in the next LBC creation or display.

LBC Application Region Highlighting Control

In previous releases of MSC.Patran when entities were added or removed from the LBC application region select databox to the textbox, the items in the textbox were always highlighted. For large models, this could take a significant amount of time.

In MSC.Patran 2005, a settings.pcl preference can be used to control highlighting. If the number of entities in the textbox exceeds “limit” only the select databox items are highlighted.

• pref_env_set_integer( "lbc_app_reg_hilight_limit", limit )

Setting the “limit” to 0 (zero) will highlight any number of entities.

In MSC.Patran 2005, the PCL command may also be used to set “limit”. This command overrides the settings.pcl preference.

• loadsbcs_selapplreg.set_lbc_app_reg_hilight_lim( limit )

4.2 Combined Vector Component PlotsThis enhancement to Results Vector Plots to support plotting sums of vector components in addition to the existing capability to plot the individual components.

This is useful, for example, to plot the resultant shear force in a fastener such as a bushing or spot weld. If the axis of the fastener is the local x direction, then the shear force can be plotted as the sum of the y and z components of the force vector.

Any combination of components or component sums may be plotted. Typically, you might only plot x and y + z, or y and z + x, or z and x + y.

To see the new toggles, just set Show As: to Component on the Results/Create/Marker/Vector/LoadCase form.

The attributes form is also changed and now has additional color selections for the new components.

Old session files producing vector plots still work as they did before this change. Unspecified new vector components are set to not display and their colors are set to default colors.

Existing Results Templates for Vector Plots also work with the enhanced tool. You can use the Tools/Results Templates/Edit form to add the new vector component toggles and colors to existing Vector Templates if you wish to do so.

4.3 Three Gigabyte Memory SupportThe 3 GB application memory option has been implemented in MSC.Patran 2005 for HP -UX on both the PA-RISC and Intel Itanium hardware platforms.

This enhancement represents our ongoing commitment to further enhance MSC.Patran's performance and large model handling ability.

This is in addition to 3 Gb application memory support on Windows XP, Windows 2000 Server, Linux, and Solaris that was done in previous releases.

There is no special setup needed on HP-UX with PA-RISC hardware. Extended addressing on HP-UX itanium is available only on OS version 11.23 and higher, and will also require an OS patch to enable the MPAS addressing model to work.

85CHAPTER 4Updates to Basic Functions

An options menu allows you to set the separator (comma is default) and whether to read the first line for Import or write column headings for Export.

Import completely replaces what is in the current spreadsheet. Export writes everything in the current spreadsheet.

Some Fields spreadsheets require the spreadsheet to be fully populated. This means there must be a dependent value specified for every combination of independent variables. The Options form from the Fields/Create and Modify forms has a frame for specifying an “Incomplete Data Action”. This tells MSC.Patran what you want it to do if there are missing values in an imported CSV file. “Abort” is the default. If it is set, and a CSV file is imported with any missing values, the import will abort with a

4.5 Pre-Release Functionality

Advanced Surface MeshingSignificant changes in the design and functionality of the Advanced Surface Meshing capability have been made for MSC.Patran 2005. Because of the extensive nature of these changes and the commitment to quality standards, the new ASM is a pre-release capability for 2005. It is being presented for your feedback on usability and suggestions on the implementation, which will help migrate this to full release status in subsequent MSC.Patran releases. To access this capability add the following line to your settings.pcl file:

pref_env_set_logical( "asm2_enable", TRUE )

Overview

Advanced Surface Meshing (ASM) is a facet geometry based process that allows you to automatically create a mesh for a complex surface model. The geometry can be congruent or noncongruent, and can contain sliver surfaces, tiny edges, gaps and overlaps. The geometry is first converted into tessellated surfaces. Tools are provided for stitching gaps on the model and modifying the tessellated surfaces as required. These modified tessellated surfaces can then be meshed to generate a quality quad-dominant mesh.

There are two kinds of representations of facet geometry in ASM process: pseudo-surface and tessellated surface. Pseudo-surface is a group-based representation and tessellated surface is a geometry-based representation. ASM uses tessellated surface representation mainly, and also uses psuedo-surface representation as an alternative tool to make model congruent. The pseudo-surface operations can be accessed if the toggle in Preferences/Finite Element/Enable Pseudo Surface ASM is on (default is off).

Tessellated Surface is piecewise planar and primarily generated for ASM process. The surface should not be modified by using the operations in Geometry/Edit/Surface form. And it has limitations on using other geometry operations on these surfaces.

Application Form

To access the ASM Application form, click the Elements Application button to bring up Finite Elements Application form, then select Create>Mesh>Adv Surface as the Action>Object>Method combination. There are 4 groups of tools in ASM process: Create Surfaces, Cleanup, Edit and Final Mesh.

Merge Surfaces Uses several criteria (4 are exposed to you) to merge the tessellated surfaces. Use the check boxes to activate and deactivate these criteria. During this operation, surfaces with edges smaller than the Edge Size specified can be merged and surfaces with Feature Angles and Fillet Angles less than that specified can also be merged. In the merging process, additional criteria are used to maximize the creation of 3 or 4-sided surfaces and reduce the number of T-sections. Surfaces that are “Fixed” will be ignored during the merging process. Vertex Angle is used to remove the redundant vertices after merging surfaces.

If Feature Angle, Fillet Angle and Edge Size are all off, the operation will merge all the connected tessellated surfaces into one surface without checking criteria.

Select Surface(s) Specify the tessellated surfaces to be merged. Need to pick at least two tessellated surfaces for this operation.

Feature Angle The Feature Angle of a surface edge is defined as the maximum angle between the normals of its two adjacent surfaces along the edge.

Fillet Angle A bent angle of a cross section on a surface is the angle between the normals of the two sides of the cross section. The fillet angle of a surface is the maximal bent angle of all cross sections on the surface.

Edge Size The size of a surface is defined in different ways. The size of a circular surface is its diameter; the size of a ring region is the length of its cross section; and the size of a 3 or 4-sided and other general region is the length of the shortest side.

Edit/Fill Hole

Fill Hole Fills the holes on the model. There are two ways to specify the hole to be filled. One is by picking all surrounding surfaces and inputting a radius tolerance. And the other is by picking at least one of boundary curves on the hole. A hole may be bounded by more than one surface.

Fill Hole(s) On Surface

Specify tessellated surfaces. The holes on the surfaces whose radii are less than the specified radius will be filled.

Hole Radius on Surface(s)

The specified hole radius.

Curves on addtl holes

Specify at least one curve on each hole to be filled.

Edit/Insert Vertex

Create New Surface

If this toggle is checked, then the hole will be filled by a new tessellated surface. If the toggle is not checked and if the hole is inside one tessellated surface, the hole will be removed from the surface. However, if the hole is bounded by multiple tessellated surfaces, then the hole is replaced by a new tessellated surface.

Feature Property

Brings up a sub-form to set, modify and show the feature properties of tessellated surfaces, including mesh size and feature state (free or fixed) of a surface.

Delete Vertex Delete vertices on tessellated surfaces. As a result, two or more edges will be merged into a longer edge. There are two ways to specify the vertices to be deleted. One is by picking the surfaces and inputting a vertex angle. And the other is by picking the vertices. Only the vertex that is used by two edges can be deleted.

Delete Vertices for Surface

Specify the tessellated surfaces.

Vertex Angle The angle of a vertex is defined as the angle formed by its two adjacent edges.
