Removing the Mesh by Domain

This task shows how to remove the mesh you generated on a single or several domains of the geometry both in the Surface Mesher workshop and in the Advanced Surface Mesher workshop.

• Open the sample08.CATAnalysis document from the samples directory.

• Enter the Surface Mesher workshop or the Advanced Surface Mesher workshop.
  For more details, refer to Entering the Surface Mesher Workshop or Entering the Advanced Surface Mesher Workshop.
  In this particular example, enter the Advanced Surface Mesher workshop.

• Mesh the surface.
  For more details, refer to Launching the Mesh Execution in the:

  • Surface Mesher workshop,

  • Advanced Surface Mesher workshop.

1. Click Remove Mesh by Domain in the Edition Tools toolbar to activate the remove mesh by domain mode.

   The Trap Type dialog box appears.

2.  Select the mesh of the single domain or domains you want to remove.

   For this You can use: Mono selection to select a single domain Multi-selection using the Trap Type dialog box using an intersection polygon trap: all the domains which have non-empty intersection with the trap will be selected. using an inclusive polygon trap: all the domains that are completely included within the trap will be selected. In this particular case click a domain as shown below: As a result the mesh of the selected domain is removed:

3. Click Remove Mesh by Domain in the Edition Tools toolbar to deactivate the remove mesh by domain mode.

   The Trap Type dialog box disappears.

Note that removing the mesh by domain is useful before Re-meshing a Domain. You can improve the mesh of a domain without removing the mesh of all the part.
