Excluding polygon geometry from abstraction

Use the Freeze Geometry command to designate faces that should be excluded from most automatic or manual geometry abstraction processes. When you use the Freeze Geometry command on a set of faces:

• The software does not perform any automatic abstraction or geometry cleanup operations on those faces during 2D or 3D meshing.

• You cannot select those faces for use with most polygon geometry commands. For example, you cannot use the Stitch Edge command to modify a face on which you have previously used the Freeze Geometry command.

You can continue to use the Split Edge and Merge Edge commands on faces that you select with the Freeze Geometry command.

Freeze_Geometry node in the Simulation Navigator

The software stores the faces that you select as a Freeze_Geometry recipe in the CAE Geometry Recipes folder in the Simulation Navigator.

You can use the Freeze_Geometry nodes in the Simulation Navigator to do the following:

• Rename the frozen geometry recipes.

• Display the locations of the frozen geometry.

• Delete selected frozen geometry recipes.

• Edit the faces in the frozen geometry recipes. You can add or remove faces from the recipe.

If you decide you want to later re-include frozen geometry in abstraction operations, delete the appropriate Freeze_Geometry node. Deleting the node does not change the polygon geometry or trigger an update of the FEM file; the faces are available for selection with manual abstraction commands and are included in any automatic abstraction operations.
