ANSYS HISTORY

� A general purpose Finite Element Analysis (FEA) package

� Founded in 1970

� Founder: Dr. John Swanson

� 1969: STASYS (Structural Analysis System)

� 1970: ANSYS

� 1975: PC version

� 2004: ANSYS 8.1 multi-physics

� 2010: ANSYS 12.1 WHAT CAN ANSYS DO?

� Structural analysis

- Stress / strain, deformation, etc.

� Thermal analysis

� Fluid flow (CFD)

� Electro magnetic

� Multi-physics (solid/fluid/electro magnetic..) HOW IT WORKS?

� Finite Element Method (FEM)

- Continuum media Piece-wised element connected by the Nodes

- Curve Pie ce-wised Line

FEM PROCESS: 3 BASIC STEPS ¬ PREPROCESSING

� Build FEM Model

♣ Geometry Construction

♣ Mesh Generation (right element type)

MODELLING APPROACH � Bottom-up approach

� Creation of model by defining the geometry of the structure with nodes and elements � Top-down approach

� Building a solid model using a 3D CAD program and then dividing the model into nodes

and elements APDL (ANSYS Parametric Design Language) � h - Method

� It is used for regular surface

� Developed in 1970s

� The name is derived from the field of numerical analysis where the ‘h’ is used for step size,

to achieve convergence in the analysis

� The h-element is always of low order, usually linear or quadratic. � p – Method

� No restrictions to shape and size

� Developed in late 1980s

� This provides option of optimizing a structure.

� p – elements can have edge polynomial as high as 9th

order, unlike the low

order polynomials of h-elements UNIT SYSTEM IN ANSYS � ANSYS had no build-in unit system

� The unit must be consistent

� The precision of results depends on the model type and mesh type ANSYS BENEFITS

¬ Simulate how a design behaves under real-world conditions without having to build costly physical prototypes.

¬ Obtain accurate results on design behavior

¬ Increase your confidence in your final product design by virtually testing a design under all conceivable

loading conditions. ANSYS APPLICATIONS

¬ Strength, durability and vibration assessment of various structures such as aircrafts, cars, trucks, or a train

¬ Structural dynamic response simulation of loads that vary with time or frequency

¬ Modal based analysis of large systems such as in automotive and aerospace vehicle systems

¬ Simulation of interior acoustics for sound pressure inside a bounded domain

¬ Static and transient analysis of structures involving material and geometric nonlinear behavior and

nonlinear boundary condition

¬ Advanced heat transfer analysis with contact including conduction, convection and radiation to understand the

effect of temperature fluctuations in consumer electronic devices such as television or cell phone.

� Automated thermal followed by structural analysis

� Analysis of structures with rotating components

� Include the effects of aero elasticity on structures

� Combined topology, sizing and shape optimization of structures with manufacturing constraints STARTING ANSYS

The ANSYS graphical user interface can be started by selecting the ANSYS icon located in the

ANSYS 12.1 Folder.

12.1

Selecting the ANSYS icon will take you directly to the graphical user interface. ANSYS Graphical User Interface

After starting ANSYS, two windows will appear. The first is the ANSYS 12.1 Output Window. This window

displays a listing of every command that ANSYS executes. If you encounter problems, this is a good place to look to

see what ANSYS is doing or has done. This is one location where you will find all of the warnings and error messages

that appear and the command that generated the warning/error.

The second window is the ANSYS Research FS graphical user interface. This is divided into 4 sections

(shown on next page):

1. ANSYS Utility Menu

2. ANSYS Toolbar Menu

3. ANSYS Main Menu

4. Display window

Each section will be discussed in further detail below.

Current Job name

ANSYS Utility Menu

Within this menu, you can perform file operations, list and plot items, and change display options. File Drop-down Menu

The File drop-down menu includes the options to clear the database, change, resume, and save the current model.

Clear and Start New deletes the current database. It does not clear the log or error

files.

Change Job name changes the name of the database and associated files. The

next time you save, it will write everything to the current job name. It will

not delete the previous job name or associated files. Note: unless you check the box for new log and error files, it will continue

to write to the current log and error files.

Change Directory allows you to switch directories where the files are being saved.

Resume Job name. db and Resume from allows you to open a model that has

already been saved. Note: If you resume a file, ANSYS does not automatically

switch the current job name to the name of the file you resumed from. Change

the job name otherwise you may write over another model.

Save as Job name. db and Save as allow you to save the model. If you choose

“save as” it will save the file as a different name. If you do not change the job

name, the next time you save it will overwrite the current job name and not

the “save as” file name.

List Pull-down Menu The list pull-down menu allows you to view the log and error files, obtain a listing of geometric entities,

elements and their properties, nodes, and boundary conditions and loads applied to the model.

This menu allows you to view the log and error files. The log file is a summary

of every command performed in ANSYS while the error file may provide insight

into troubleshooting problems with the model/analysis.

These list the geometric entities and their components.

Selecting the Nodes and Elements listings are easy methods to determine the

number of nodes and elements in the model.

Plot Pull-down Menu

This pull-down menu allows you to plot the various components of the model such as key points, areas,

volumes and elements.

Use the plot elements command to obtain the mesh plot.

PlotCtrls Pull-Down Menu This menu includes the controls to pan/zoom/rotate your model, select the numbering options, change styles

and generate hard copies of the plots.

This pops up a window allowing you to pan, zoom and rotate the model.

The Numbering selection allows you to turn on/off the key point,

lines, areas, volumes, nodes and element numbering.

The Hard Copy selection sends the plot to a printer or image file.

ANSYS Toolbar

If you get a message reporting that the percent error cannot be calculated with

power graphics turned on, click the POWRGRPH button to turn off power graphics.

ANSYS Main Menu

The ANSYS Main Menu contains all of the commands to create, mesh, apply loads, solve, and view results of the FE analysis. The Main Menu is divided into sections that sequentially follow the steps involved in an analysis.

Preprocessor

Select the element types to be used. Multiple types may

be selected and applied to a model.

Input the material properties. Multiple materials may be entered and

applied to a model.

Use the modeling options to create the model. Note: ANSYS uses a

hierarchy for modeling: Keypoints

(lowest) lines Areas Volumes (highest)

If you create a volume, all of the areas, lines and key points will

be automatically created for you.

Use the meshing options to mesh the model.

To delete mistakes, choose the Delete menu under Modeling. It is

important to select the right option. For example, if you select Areas

only, the area will be deleted but the lines and key points that make

up that area will remain. If you select Areas and below, it will delete

the area plus the lines and key points that define the area.

NOTE: there is not an undo button in ANSYS, once deleted, the

component must be re-created.

Solution

Choose the type of analysis to perform.

Apply loads and boundary conditions to the model.

Solve the model.

Post Processing

Plot contour or vector plots of results.

Lists the percent error. If you get a message “Cannot view

percent error with power graphics on”, click the power graphics

button on the ANSYS Toolbar to turn it off.

List the results for every node. This can be used to get the

maximum and minimum values of results.
