HVVH-5000: FE Model Tab

In this tutorial, you will learn how to perform model setup in HyperMesh and identify problems during the interactive HyperMesh operation.


FE Model Setup - First Use Case

In this step you will perform the FE Model setup using the Model Setup tab.

  1. From the FE Model tab, select the Model Setup tab.


    Figure 1.
  2. From the Solver Type list, select OptiStruct.
  3. From the HW Version list, select 2021.
  4. Click the Modify script/cmf checkbox.
  5. Do not select the Config file or Models option.
  6. Under the Script/cmf files section, click the file browser icon, , or the add file icon, , to load the Plate.tcl file, located in ..\tutorials\hvvh\FEModel\ModelSetup.
  7. In the Output directory field, click to select an output directory.
  8. Click Run.


    Figure 2.

    The model file with the script is imported and a set of operations in HyperMesh are executed. The status is displayed under Model Setup info.

    If the selected Tcl file is executed correctly and there are no problems with the HyperMesh operations, the status displays Pass.

    In the Messages window, the run details and the log file location are displayed.
