Proprietary Information of Altair Engineering


Connectors

New FeaturesHAZ remesh upon connector unrealization

Remesh or Rebuild HAZ elements, and specify the number of layers to be considered around HAZelements for remesh or rebuild using the new Unrealize remesh or Rebuild optionOnly available in the Entity Editor for connectors that create HAZs.

Test point alignment for Seam connectorsImprove mesh flow by aligning test points based on proximity of other connectors using thenew Seam test Points Alignment option. This option also ensures cross-over connectors havecommon test points to allow unique nodes to be created.When the Seam test Points Alignment option is enabled, additional options also becomeavailable to help you further define how seam test points are aligned. Enabling the Seam LooseEnds option will only allow seam connectors which have free ends to be considered. Enabling theSeam Fixed option will only allow seam connectors which have fixed nodes at the ends to beconsidered and left undisturbed.

EnhancementsUnrealize connectors with remesh/rebuild performance

When unrealizing connectors, the performance of remeshing/rebuilding multiple small areaswithin a large model has significantly improved.

Connector Entity Editor performanceThe display of connector attribute data populated in the Connector Entity Editor when a largenumber of connectors are selected in the Connector Entity browser has improved significantly.

Quad-Seam FE absorptionFE absorption of quad element clusters is now supported for second order elements.Closed loop/rounded quad element clusters can now be absorbed as quad seam connectors.Quad clusters with caps can now be absorbed as seam quad LTB connectors.

Absorption of multilayer if weld element body is disconnectedFE absorption has been enhanced for bodies separated on both sides of a layer. When a body hascoincident nodes on both sides of a layer, it is absorbed as a single connector and not absorbed asmultiple connectors.

Resolved Issues• Quad seam connector absorption issues when HAZ elements are not present.

• HAZ component is absorbed as a connector link, while FE is absorbing quad seam connector.

• Hexa Nugget connector fails when close to 1D elements.

• Various issues with mesh being distorted when realizing hexa nugget connectors.

• Issue with the transformation of the orientation vector for Bolt (cylinder) connector.

• Command *CE_GlobalSetString is supported for undo/redo.

• *CE_ColinearityCheck is supported as ‘no action’ command for undo/redo.

• Miscellaneous robustness and performance improvements.

EnhancementsMidsurface undo/redo support

Undo/redo functionality is now supported for midsurface commands and panels.

Resolved Issues• Miscellaneous robustness and performance improvements.

2D Meshing

EnhancementsLocal Remeshing Performance

The performance of remeshing multiple small areas within a large model has been significantlyimproved. This applies to all remeshing operations and tools that may utilize remeshing, includingautomesh, rebuild, imprint, connector realization/unrealization, topology revision, and manyothers.

BatchMesherUpdates have been made to improve the mesh flow near holes and washers. Generalimprovements have also been made to resolve issues with bead recognition, proximitysuppression, washer creation for user-defined holes, and element quality correction.The BatchMesher config file can be edited to replace file paths with environment variables thatdefine the path locations. This helps with automation, as well as portability across platforms.

Parameter and Criteria EditorsThe Parameter and Criteria editors have been modernized and reorganized to improve usability.The criteria file now additionally supports storage of the 3D criteria, along with the criteria colorsand order, and the QI colors.

MidmeshEdges which do not have clear intersection directions are now aligned automatically directlybeneath the geometry edges (that is, steps and fillets) when flattening is enabled.Imprinting of edges from both sides of the input geometry is improved. Previously, only the edgesfrom the side from which the mesh was offset were preserved, which led to inconsistencies incapturing.Rib end edges are now automatically extended to nearby boundaries to create additional trimlinesleading to improved remesh/rebuild output.Improved the node distribution at free edges with fillets.Flattening has been improved to reduce downstream problems like folds, holes, slivers andunimprinted ribs or edges.Multiple bug fixes and general improvements have been made for the midmesh editing tools.



Rebuild MeshConstrained movement of nodes associated to surface edges or 1D topology edges is nowsupported to better correct element quality during rebuild. The movement is optional and iscontrolled by the Move across free edges and Move across non-manifold edges options inthe parameter file.

Surface DeviationImprovements have been made to avoid intersections for sharp and close-proximity locations, andto maintain the association with the geometry for sharp corners and sliver surfaces.

Adaptive Tria RemeshingSignificant improvements for size transitions have been made, along with increases in theperformance. The robustness of remeshing a wrapped model is also improved.

Resolved Issues• Corrected the aspect ratio calculation for Abaqus to be the ratio of the longest edge to the shortest

edge.

• Miscellaneous robustness and performance improvements.

• Bulk Material interaction with EDEM

• Enhancements

• Known Issues

• Resolved Issues

General

New FeaturesSupport for Functional Mockup Unit (FMU)

MotionView now supports adding a Functional Mockup Unit (FMU) to an MBS model solving inMotionSolve. A FMU is a system based on a tool independent standard called Functional Mock-up Interface (FMI) that supports exchange and co-simulation of dynamic models. Using a FMU,systems from diverse domains or applications can be coupled to generate high fidelity dynamicmodels.For more information, refer to Functional Mockup Unit (FMU).

Bulk Material Interaction through EDEMMotionSolve has a new coupling interface in a bulk material simulation tool called EDEM®

(registered trademark of DEM Solutions Ltd.) This utility is available in MotionView to makethe connection, transfer geometries to EDEM, and run the simulation. Typical applicationsinclude interactions of multi-body models with granular materials such as powders, sand, rocks,agricultural produce, pharmaceuticals, and so on.For more information refer to Bulk Material Interaction.

Analytical rigid body 3D contactNew in this release is the ability to compute 3D contact kinematics (location, normal andpenetration) analytically for simple shapes. Support for contact between different geometrycombinations is shown in Figure 9.


../../../mv/topics/chapter_heads/functional_mockup_units_fmu_r.htm

../../../mv/topics/motionview/bulk_material_interaction_r.htm


Figure 9: Contact Kinematics Calculation Methods for Supported Geometries

A change to this effect is done in MotionView export of solver deck XML for contacts. The attributeenable_analytical = "AUTO" is included in the Force_Contact statement.

EnhancementsSupport for Output component names and units

A custom name and unit information can now be provided for Expression outputs. A .NAM file isalso written to enable you to view those component names while plotting in HyperGraph.

Additional entities covered in export to MotionSolve PythonCoverage for export to MotionSolve Python has been extended in the following entities:SolverString, ControlSISO, ControlStateEquation, Graphics: Tire, Tube and DeformableSurface.


• MDL exported from the Run settings of Inspire-Motion 2019.2 using the option of MotionView2019 or older mdl file could fail to read successfully in MotionView 2019.1 for Inspire models thatcontain assemblies and part instances. For such models, it is recommended to use the MotionView2019.1 or newer mdl file option.

• MotionSolve gives errors while using a flexbody generated from MotionView v2019/2019.1 via themirror option or conversion from mnf to h3d.

Resolved Issues• Dummy body is not created when a user defined Force has a CMS Flex body as J Body (Body 2).

• The CG inertia Summary tool returned erroneous inertia values for flexbodies which used BodyCoordinate Systems other than Global Frame.

• Missing scroll bar in the Expression Builder.

• Certain graphics that have their visualization settings set to transparent would lose this settingwhen changing visualization settings for other graphics.

• Linux version of 2019 had issues of truncated displays in certain panels and dialogs.

• Translation of Abaqus FIL to Altair MRF not working.

• The following issues with the Optimization Wizard and export to MotionSolve Python in 2019 havebeen addressed:



◦ Using of copy/paste functionality on bounds and nominal values result in an application error.

◦ ActionReaction Force Marker J not exported.

◦ Coulomb friction for Contact entity not exported.

◦ is_material_inside attribute on Graphics not written.

Automotive Solutions

EnhancementsAltair Driver Feedforward Steer Controller mode for low speed events

The Feedforward Steer Controller now offers a kinematic bicycle model option for events run ata low speed. If you simulate parking events or other low-speed events and find that the steeringcontroller does not converge, then using the kinematic bicycle model may help you achieve goodresults.To select the kinematic bicycle model, set CONTROL_MODE = 0 in the steering control block of theAltair Driver File (.adf) as show below:

$----------------FEEDFORWARD_STEERING [FEEDFORWARD_STEERING] TAG = 'FEEDFORWARD' CONTROL_MODE = 0 LOOK_AHEAD_TIME = 0.5

Altair Driver offers option to free the steeringSome events require the driver to achieve a certain lateral acceleration and speed in order to freethe steering wheel. Altair Drive now adds an open loop control type to free the steering wheel. Tofree the steering use the following in the Altair Driver File (.adf):

[MANEUVER_2] TASK = 'STANDARD'(CONTROLLERS){DRIVER_SIGNAL PRIMARY_CONTROLLER ADDITIONAL_CONTROLLER} STEER OL_STEER NONE

[OL_STEER] TAG = 'OPENLOOP' TYPE = 'FREE'

nPost Signal Manager adds X-OffsetYou can offset any input signal in time by setting a X-offset value. Different X-offsets may be usedfor different signals. By default, the X-offset value is zero.



Road Tools now supports road data files (.rdf) that reference openCRG road filesYou can now enter a road data file (.rdf) that references an openCRG road file. The Road Toolswill create graphics based on the openCRG road file. Previously you had to enter the openCRG filedirectly in the Road Tools to create graphics.

Road Tools add supports for 3D Spline Road FilesYou can now create graphics for 3D Spline road data files using Road Tools. The graphics createdcurrently depict only the base road given by the table of the road center line and width in the roaddata file. Overlain obstacles, such as a pot hole, are not rendered.

FIALA Elliptical Cam Tire-Road Contact Performance ImprovesPerformance of the Elliptical Cam Tire-Road contact model is improved by 10%.

Resolved Issues• CDTire: Previously when using CDTire, if the tire lost contact with the road the free rolling speed

of the tire was reported as -9999 radians/s. In 2019.1, if the tire loses contact with the road thefree rolling speed is computed as the longitudinal velocity of the wheel and tire divided by the tire’sunloaded radius (Vx/R0).

• Full Vehicle Events are now linked to online help by pressing F1. When you select a full vehicleevent in a model, pressing F1 launches your preferred bowser and displays the online help for theevent.

• Leaf Spring Builder: For leaf springs using the Design Shape Condition, the SAE J510 test nowallows the spring to relax to its free position before starting the test.

• Leaf Spring Builder - Incorrect Shackle length: When you specified a shackle length and offset andset the spring mounting length (Lcc) to zero, the location of the shackle point (shackle-to-frame)was incorrectly calculated shortening the shackle. The shackle length is now maintained.

• Leaf Spring Builder - Design Shape Condition - Leaf Spring Pre-loads have wrong sign: Previouslyfor Design Shape Condition, the leaf spring builder computed the leaf pre-loads with the wrongsign. If you simulated allowing the leaf spring to relax to its free position, the spring would deflectupward instead of downward. The pre-loads now have the correct sign.

• MDLLIB: Missing Differential Carrier Graphics in live_axle.mdl. Previously, if you built a rear halfvehicle or full vehicle with a driven solid axle and live axle driveline using the model wizard, thegraphics for the differential carrier were missing because of an error in the file: …\hw\mdllib\Libs\Models\Driveline\Rear\Axle\live_axle.mdl. The error is corrected.

• MDLLIB: Duplicate tire graphics in Solid_axle_susp_leaf_spr.mdl. Previously, if you built a fullvehicle with a solid axle and leaf spring rear suspension using the model wizard, the tire graphicswithin the rear solid axle suspension used for suspension analysis were not deactivated. Theproblem is corrected.

• The nPost panel layout has been improved so that the Apply-to-all button for setting the tireunloaded radius and stiffness on all tires is not obscured.

• The nPost shaker event adds appropriate graphics auxiliary posts.



Figure 10:

• The nPost shaker event includes wheel and tire mass and graphics when you select tire coupling.When your model employs autoTire systems and you select tire coupling, the wheel and tire massand graphics are now retained from the autoTire systems for nPost simulation. However, the tireforce within the autoTire systems are deactivated and the linear stiffness and damping values youset in nPost event couple the posts to the wheels.

• The nPost shaker event signal type for single-wheel posts now match the signal type for paired-wheel posts. Previously, single-wheel posts incorrectly inherited their signal type (for example,displacement, acceleration, force) from auxiliary posts.

• The nPost shaker event now checks for posts without input signals when you run the event offeringyou the choice to abort the run to assign signals or continue.

The status of the bodies aredynamically updated based on geometric modifications. Right-click context menus provide optionsfor visualization, organization, and fixing geometry automatically.

Workflow helpWorkflow help guides you through the steps to follow within each tool. Workflow help comes witha brief short description about the steps, some insight into the tools, and keyboard shortcutsand mouse controls. Some tools also have a short video explaining the workflow. Workflow helpenables you start quicker without having to go back and forth between the software and helpdocumentation.

Search toolThe search tool enables you to find open the tools that are available on the ribbons. You cansearch for a tool with a keyword or using the entire name. Predicated results appear in a list.Clicking on any of options opens the corresponding tool.

Geometry ToolsContextual tool interactions

New geometric tools enable you to interactively create geometries using previews and on-screenwidgets. Geometric editing tools provide you the option to find relevant targeted regions, navigatethrough them one by one, and fix them. Many tools provide run-time options to automatesubsequent steps after geometric operations. Tool guide bars are designed to guide you throughthe workflow as you make selections.

Tool to extract fluid volumes - PlugNew tool to detect and fill cavities of solid parts, which is required for most of CFD modelpreparation. This tool provides you the option to detect cavities automatically or by supplyinginformation about bounds and a single cavity surface. The tool enables you to navigate througheach cavity and fill then individually or all in one go.



Defeaturing toolsA new defeaturing tool set is provided in the Geometry ribbon. The defeaturing tool set enablesyou to simplify the geometric model by removing holes, fillets, logos, small features. The Batchrepair tool enables you to run all repair and defeaturing options in one go.

FE geometry engineA new FE geometry engine enables you to maintain the same workflow for CAD and FE geometryinput. When importing an FE model, the engine generates FE geometry with topological points,lines, surfaces, and solids. All geometric creation, editing, and a few defeaturing tools work on FEgeometry as well. All visualization tools and selections work the same way as on CAD geometry.

Geometry model validationThe Validation tool enables you to validate the geometry before model setup and meshing. Thetool provides the capability to list geometric issues in the model, review them, and automateoptions to fix them. Validating geometry ensures smooth flow for model setup and meshing.

Model SetupFlow, thermal, motion physics support

The new HyperWorks CFD X GUI enables you to set up flow, thermal (heat transfer, thermalradiation, solar radiation) and motion problems. Flow-thermal, radiation, and motion physicssetup tools are organized in separate ribbons.

Interactive color-coded setup with GUI widgets, plotsWidgets, color-coded legends, microdialogs, and plots enable easy setup for complex simulations.Guide bars navigate you through multi-step setup. The setup tools incorporate:

• Color-coded legends that enable you to review and edit setup.

• GUI widgets to interactively set up axes, directions, systems, and degrees of freedom.

• Plots to enable easy setup for varying properties.

Default wall handlingDefault wall enables you to just define setup on boundaries with specific conditions. All walls,including interface walls, no slip walls, and walls with rotating reference frames are handledautomatically.

Conflict resolutionWhile you are setting up the model, tools automatically resolves any conflicts in the selections tomaintain uniqueness and avoid failures when running the simulation.

MeshingOne-click meshing

The meshing workflow is defined in a way to enable one-click meshing. Once you define controls,you can run surface and volume mesh in one go. The meshing process also takes care of solver-specific meshing requirements, such as generating mapped mesh for periodic surface sets andnot generating boundary layers on solid volumes. Many checks and fixes are performed to ensurethe success of the meshing process, such as checking for geometry validity and checks for validsurface mesh before volume mesh. In the case of failure, you are directed to the failed region.



Surface meshing robustness improvementIn order to achieve true one-click meshing, the surface mesher is improved to avoid failures likeunmeshed surfaces, bad element transition, and self-intersections. With the new mesher, youget good transition with user-defined sizes and refinement zones, and good mesh–geometryassociation.

Surface meshing, volume meshing performanceNew technologies bring in higher performance standards with respect to both speed and memory.Lean memory of meshers enables generating volume mesh of order 100 mi on a 32 GB machine.

Improved large volume mesh handlingImproved handling of large volume mesh to load/render a model with volume mesh of order of100 mi elements on 32 GB RAM machine. You can use the section cut tool to review mesh.

Integrated solver RunRun monitors, log files

Once the Acusolve job is submitted from the GUI, the run manager enables you to review thestatus, the solver log file, and the convergence-monitoring plots. The run manager can listsmultiple job and their status.

Improved export performanceImproved performance for large volume mesh export. A 200 mi element flow model can beexported in under a minute.

Known IssuesThe following known issues will be addressed in a future release as we continuously improve thesoftware:

• No checks for self-intersecting geometry

• Geometry combines for complex geometries

• Surface meshing robustness for untrimmed complex surfaces and sliver surfaces

• No volume element quality visualization

• No support for 2D simulations with extrusion

• Setup validation is missing, a case of wrong properties and conflicting physics setup will not becaught
