In Mesh module it is possible to create groups of mesh elements: nodes, edges, faces or volumes. One group contains elements of only one type. The following ways of creation are possible:
- by selecting the elements using filters and/or directly on the presentation in the VTK viewer, and/or by using elements of other mesh objects - Standalone group tab of Create group dialog.
- by creating a group of elements generated on the chosen geometrical object - Group on geometry tab of Create group dialog and Create Groups from Geometry dialog.
- by creating a group of elements satisfying to certain criteria - Group on filter tab of Create group dialog.
- by creating groups of nodes and elements from the chosen submesh (type of elements depends on dimension of submesh geometry) - using Mesh -> Construct Group menu item (available in context menu as well).
- by creating groups of entities from existing groups of superior dimensions - using Create Group of Underlying Elements dialog.
The created groups can be later:
An important tool, providing filters for creation of Standalone groups is Selection filter library.
