Meshed geometry is ready for solver analysis once suitable material, property, loading and boundary conditions are applied to the model.  Reading in and writing out the model in a pre-processor should not result in any loss of data, change in the quality of the mesh, model, and so on.  Also, from a customer perspective, having full coverage for the “most used keywords based on analyses” is important to get an accurate result.

This facility should help you cover the above aspects; further details of the same are given in each of the options.  Special cases (for Ls-Dyna) and input/output operations (for most of the solvers) using HyperMesh and HyperCrash, are covered.  Checking the quality of the model through the model checker capability further augments the verification and validation process.  Provisions are also given to check the accuracy of data from the solution point of view using Check run, which triggers the solver (you must have a solver license) for the model check run.

Reports are generated at different levels to validate the model, including the basic model check run or zero millisecond run, for crash solvers.

Solver Type

From the Solver Type drop-down menu, select a solver type.  Options include:

RADIOSS(BLOCK), OptiStruct, Abaqus, Ansys, LsDyna, Madymo, Marc, Nastran, Pamcrash2G, Permas, and Samcef.

HW Version

Select the HyperWorks version number from the drop-down menu.

Modify cmf script

If this option is activated, it replaces all HyperWorks paths with the selected HyperWorks version and generates a new copy(copies) of the .cmf file(s).

Model (Solver Deck/HM File)

Deactivate this check box if there are no models to load. Or, activate the check box to load a solver deck model or HyperMesh file.

Click in the cell for each file type to activate it.  Once the cell is active, clickadd_file_iconto display the file browser and load only the selected file(s). You can also add multiple files.

Clickdelete_file_iconto delete a selected file from the list.

Note: Only one file is supported at an instance.

Scripts/cmf Files:

Click file_folder below the list box to select a folder that contains multiple script files (Tcl/Tcb) or cmf files. You can select the top level folder and load all files of the selected file type.

Environment Variables

You can set the environmental variables in the config file.

1.If ModelSetup is 0: Execute hmbatch.exe.
2.If ModelSetup is 1: Execute hmopengl.exe.
3.If ModelSetupConfig is 0: Reads the config file but doesn't replace the paths (only reads the ModelSetup variable).
4.If ModelSetupConfig is 1: Reads the config file and replaces all paths in the CMF files.

Run

All selected scripts/cmf files are run in the (solver deck model/HyperMesh model) batch mode.

If no models are selected, then the scripts/cmf files are run batch mode.  In this case, the model should be read through scripts/cmf files.

HyperMesh(hm) and solver deck files are saved to the output directory. Click the Status button to browse to the output directory.

hmtoggle_plus1greyBasic Input and Output

Using the Basic IO tab, you can verify that HyperMesh and HyperCrash do not deprecate any model during import and export. The show different report identifies any loss or change of data.

The verification and validation levels include:

•Two stages of verification.

- Reference model file with the exported file.

- Model check report of the reference file and the exported file.

Note:     In the absence of a model checker for a given solver, the FE entity counts are compared.

•Import/export timing and the status.
•Diff report.

- Input/output files.

- Model checker output information OR FE entity counts.

- Solver results with check runs.

•Solver Check RUN (IMPORTANT)

- Exported file solver result comparison with the reference model result, after the solver check run.  This checks whether the solver deck is a valid solver deck.

Note:     Both runs are with the same solver version.
