CAPABILITIES

OVERVIEW

MSC.Patran 2003’s Advanced Surface Mesher will greatly enhance andstreamline your ability to handle complex or "dirty" surface finiteelement models.

Advanced Surface Mesher radically reduces the level of user-interactionneeded to clean up non-congruencies, gaps, overlaps, and slivers. Thesame complex part can now be meshed in a fraction of the time that itused to take, offering a significant improvement in productivity andefficiency.

Pseudo face (initial mesh) creation

• Pseudo faces can be created with minimal geometryediting- No geometry-based correction of non-

congruencies, gaps, overlaps and slivers is needed

• Automatic

Additional mesh-simplification tools areavailable to accommodate specificanalysis needs:

• Fill Holes (with radius)• Fill Holes (with specific nodes)• Merge Face• Auto Correct• Collapse Edge• Split Face

Non-Congruent Surface

boundaries

Gap

FEM Editing

• Clean-up tools are available to yield high-quality, analysis-ready models- Automatic and manual tools- Make Congruent

◆ Sew pseudo faces based on pre-determinedtolerance

- Stitching◆ Close gap based on selected edges. No

tolerance check- Delete Face

◆ Delete selected pseudo faces. - Verify Free Edges; Display Small Entities; Display non-

manifold edges

Merge faces into one face

Final Mesh

• Global control of element size• Hard-geometry recognition

- Hard points and curves• Additional mesh controls

- Local control mesh size and pseudo faces
