On this tab, the native CAD model is imported into HyperMesh and exported using CAD readers in HyperMesh that are run in the background.  The exported model is re-imported and overlaid.  With superposed models using advanced CAD-CAD comparison, any loss of geometric data is identified, along with any entity changes.  A reference report is also created.

Import file type

From the drop-down menu, select the CAD input file.  Supported file types include:

Export file type

From the drop-down menu, select the output file type.  Supported output file types include:

HW Version

Select the HyperWorks version number from the list.

Tolerance

Native Reader

Enables a native reader, requiring original CAD software and licenses, to be used. Only available for the UG format.

This method of import, along with feature-based meshing technology, provides a robust way to create high-quality CAE solid tetrahedral mesh models without a lot of geometry cleanup.

The native CAD model is imported into HyperMesh along with a user-defined parameter and criteria files.  The CAD model is batch meshed and the finite element (FE) mesh created is compared with the CAD model using advanced CAD-FE comparison.  A reference report is also created, indicating any change in the meshed profile with respect to geometry.

CAD > Mesh tab

HW Version

Select the HyperWorks version number from the list.

Tolerance

The tolerance value to use for the comparison.

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.

Input file(s)

Use this section to load a CAD model file(s), parameter file(s) and criteria file(s).

CAD > Mesh

The CAD model is converted to FE Mesh using the Batch Mesher (the criteria and parameter files are the input data).

The CAD > FE comparison report is generated for the HyperMesh finite element mesh and the original CAD file to report the accuracy or deviation from the original geometry and meshed data.

Under Mesh Status, click Status to return the status of the meshing operation.  In case of failure, it will indicate the same.

Under Report, click Report to return a report that compares the CAD and FE model.  The report is written to a text file.

Compare

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).

Compare Mesh

The CAD > FE comparison report is generated for the HyperMesh FE meshed files across different versions of HyperMesh.

Current Mesh Status - Under this 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.

Reference Mesh Status - Under this 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.

Report - Under this 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.
