5 In Mesh module it is possible to create groups of mesh elements:
6 nodes, edges, faces or volumes. One group contains elements of only
7 one type. The following ways of creation are possible:
9 - by selecting the elements using filters and/or directly on the
10 presentation in the VTK viewer, and/or by using elements of other
11 mesh objects - \ref standalone_group "Standalone group"
12 tab of \ref creating_groups_page "Create group" dialog.
13 - by creating a group of elements generated on the chosen geometrical
14 object - \ref group_on_geom "Group on geometry" tab of
15 \subpage creating_groups_page "Create group" dialog and
16 \subpage create_groups_from_geometry_page "Create Groups from Geometry"
18 - by creating a group of elements satisfying to certain criteria -
19 \ref group_on_filter "Group on filter" tab of
20 \subpage creating_groups_page "Create group" dialog.
21 - by creating groups of nodes and elements from the chosen submesh
22 (type of elements depends on dimension of submesh geometry) -
23 using <b>Mesh -> Construct Group</b> menu item (available in context
25 - by creating groups of entities from existing groups of superior
26 dimensions - using \subpage group_of_underlying_elements_page
27 "Create Group of Underlying Elements" dialog.
29 The created groups can be later:
31 - \subpage editing_groups_page "Edited"
32 - \subpage using_operations_on_groups_page "Subjected to Boolean operations"
33 - \subpage deleting_groups_page "Deleted"
35 An important tool, providing filters for creation of \b Standalone
36 groups is \ref selection_filter_library_page.
