Groups in Nonlinear Structural Analysis and Thermal Analysis

This appendix describes how you can use groups with Nonlinear Structural Analysis and Thermal Analysis. All of the CATIA V5 groups are supported by the Nonlinear Structural Analysis and Thermal Analysis workbenches. Each type of group is described in Creating Groups.

The following tables indicate when you can use a group as a support for an Nonlinear Structural Analysis or Thermal Analysis feature, such as a boundary condition, a load, or a contact definition. A table is provided for the following types of groups:

Table B–1 shows the support for geometrical groups in Nonlinear Structural Analysis and Thermal Analysis.
