Lesson 1 3Computational Mechanics, AAU, EsbjergANSYS
What is ANSYS• ANSYS finite element analysis software enables
engineers to perform the following tasks: – Build computer models or transfer CAD models of
structures, products, components, or systems.– Apply operating loads or other design performance
conditions.– Study physical responses, such as stress levels,
temperature distributions, or electromagnetic fields.– Optimize a design early in the development process to
reduce production costs.– Do prototype testing in environments where it otherwise
would be undesirable or impossible (for example, biomedical applications).

• You can access the following file operations from the session editor dialog:
– OK: Enters the series of operations displayed in the window below. You will use this option to input the command string after you have modified it.
– Save: Saves the command string displayed in the window below to a separate file. ANSYS names the file Jobnam000.cmds, with each subsequent save operation incrementing the filename by one digit. You can use the /INPUT command to reenter the saved file.
– Cancel: Dismisses this window and returns to your analysis.
– Help: Displays the command reference for the UNDO command.
During an analysis, you may want to modify or deletecommands entered since your last SAVE RESUMEor .
The Session Editor is available in interactive (GUI) mode only.
