Geometry Groups

Groups provide a powerful capability for performing operations on multiple geometric entities with minimal input. They can also serve as a means for sorting geometric entities according to various criteria. The following describes the Group operations available in Trelis:

When a group is meshed, Trelis will automatically perform an interval matching on all surfaces in the group (including surfaces that are a part of volumes or bodies in the group).

There are several utilities in Trelis which use groups as a means of visualizing output. These utilities are described elsewhere, but listed here for reference:
