Re-meshing Triangular Domains with Mapped Mesh

This task shows you how to re-mesh a triangular domain using the mapped mesh method.

• Open the Sample22.CATAnalysis document from the samples directory.

• Enter the Surface Mesher workshop.
  For more details, refer to Entering the Surface Mesher Workshop.

1. Click Mapped Method for Triangular Domain in the Local Specifications toolbar.

   The Mapped Mesh for Triangular Domain dialog box appears. Support: lets you select the triangular domain you want to re-mesh using the mapped mesh method. Impact neighbor domains: lets you define whether you wish to apply the new mesh method to the neighboring domains. If the option is deactivated, the nodes on domain edges will not be modified. Mesh size: lets you specify the size of the mapped mesh for triangular domain.

2. Select a triangular domain as Support.

   In this particular example, select the following domain:

3. Clear the Impact neighbor domains check box.

4. Enter the value of Mesh Size.

   In this particular example, enter 10mm as Mesh size value.

5. Click OK.

   A Mesh Specifications.1 set containing the Mapped Mesh for Triangular Domain.1 specification appears in the specification tree under the Surface Mesh.1 mesh part. The triangular domain is now meshed.
