Re-meshing Domains with Frontal Triangle Mesh

This task shows you how to re-mesh domains using the frontal triangle mesh method.

• Open the Sample15.CATAnalysis document from the samples directory.

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

1. Click Frontal Triangle Method in the Local Specifications toolbar.

   The Frontal Triangle Mesh dialog box appears. Support: lets you select the domain you want to re-mesh using the frontal triangle 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 frontal triangle mesh.

2. Select a domain as Support.

   In this particular example, select the following domain:

3. Enter the value of Mesh Size.

   In this particular example, enter 6mm as Mesh size value.

4. Click OK.

   A Mesh Specifications.1 set containing the Frontal Triangle Mesh.1 specification appears in the specification tree under the Surface Mesh.1 mesh part. You can see that the domain has been re-meshed:

5. Edit the mesh specification you just created.
   To do this, double-click Frontal Triangle Mesh.1 in the specification tree.

6. Select the Impact neighbor domains check box.

7. Click OK.

   The neighbored domains are also re-meshed:
