In Mesh module it is possible to create groups of mesh elements: nodes, edges, faces or volumes:
-
by selecting the elements of the specified kind by their IDs or directly on the presentation in the VTK viewer - Standalone group tab of Create group dialog.
-
by creating a group of elements of the selected type from all such elements of the chosen geometrical object - Group on geometry tab of Create group dialog.
-
by creating a group including all types of elements from an existing geometrical object - using Create Groups from Geometry dialog.
-
by creating several groups of elements (nodes, edges, faces and volumes) from the chosen submesh - using Mesh -> Construct Group Menu item. In this case groups of elements are created automatically.
-
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.
