Simplifying the Geometry

This task shows how to simplify the geometry in order to improve the quality of the mesh.

Open the sample05.CATAnalysis document from the samples directory.

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

1. Click Global Meshing Parameters in the Global Specifications toolbar.

   The Global Parameters dialog box appears.

2. Select the desired parameters and click OK in the Global Parameters dialog box.

   For more details about this dialog box, refer to Setting Global Meshing Parameters.

3. Click Geometry Simplification in the Execution toolbar.

   A set of optimized constraints is computed.

• Geometrical simplification is always done, before meshing, even if you do not launch it.

• Determine if you have to modify manually the specifications before the meshing.

• Simplify the geometry to preview the domains.

• If needed, modify the specifications:

  • Remove the geometrical simplification.
    For more information, refer to Removing the Geometrical Simplification.

  • Define the desired specifications.
    For more information, refer to Local Specifications toolbar.
