Pre-processor Verification and Validation (CAD Modeling and Meshing)
CAD IO
- Check for loss of geometry information during CAD I/O for different CAD-HM interfaces.
- Compare exported CAD models with the re-imported model (CAD-CAD comparison; HyperMesh APIs used).
- Perform entity comparison, surface area comparison, check for matched/unmatched overlapped areas, intersected regions, and surface meta data information.
CAD Model Comparison Across HyperMesh Versions
- Similar to CAD I/O, except two exported CAD models are compared from different HyperMesh versions using CAD-CAD comparison APIs.
CAD-Mesh Comparison
- CAD model is auto-meshed and the meshed model is compared with the original geometry to see how well the geometric surface is captured in the FE model.
- Report deviations in the CAD-MESH region comparison.
- Surface area comparison.
- Matched/unmatched, overlapped, intersected regions.
Meshed Geometry Comparison across HyperMesh Versions
- Check the consistency of the meshed geometry.
- QI and other element checks are compared along with surface area comparison, matched/unmatched overlapped, intersected regions, using FE-FE comparison HyperMesh APIs.
- Geometric Entity Count and Comparison
- Points, Lines, Surface, Solids, Assemblies, Components Quality Index
- Surface Area Comparison
- Matched, overlapped, intersected, unmatched
