Compare FE Meshes

The native CAD model is imported into HyperMesh along with a user-defined parameter and criteria files in two different HyperMesh versions. CAD models are batch meshed and FE meshes are superposed. Using advanced FE-FE comparison, any change in mesh quality are identified and reported.

1. Click the CAD tab then the FE-FE tab.

   
   
   Figure 1.

2. Select the current and reference solver version.
3. Enter a Tolerance value for use in the comparison.
4. Activate any of the check boxes to assist in loading files.

   Option	Description
   Same as Criteria	If there is more than one model file loaded in the input table, there is no need to load the Criteria file in each row. If you activate this check box, HVVH loads the first Criteria file in each row for all selected input files
   Same as Parameter	If there is more than one model file loaded in input table, there is no need to load a Parameter file in each row. If you activate this check box, HVVH loads the first Parameter file in each row for all selected input files.
   BM (Batch Mesher)	This check-box allows you to load a batch mesher session file and executes the batch mesher.

5. Use the Input file(s) section to load a CAD model file(s), parameter file(s) and criteria files(s).
   Tip:

   • Click in the cell for each file type to activate it. Once the cell is active, click to display the file browser and load only selected files. You can also add multiple files.
   • Click to add a row to the table.
   • Click to delete a row from the table.
6. Select an output directory.
   The CAD models are converted into FE meshes via batch mode, using the criteria and parameter files, in two HyperMesh sessions (also in two different versions).
7. Click Compare.
   The CAD > FE comparison report is generated for the HyperMesh FE meshed files across different versions of HyperMesh.

   Under the Current Mesh Status heading, click Status to return the status of the meshing operation on the CAD model using the current HyperMesh version. In case of failure, it will indicate the same.

   Under the Reference Mesh Status heading, click Status to return the status of the meshing operation on the CAD model using the reference HyperMesh version. In case of failure, it will indicate the same.

   Under the Report heading, click Report to return a report that compares the FE model generated using the current version of HyperMesh and the FE model generated using the reference HyperMesh version. The report is written to a text file.
