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:
10 <li> by selecting the elements using filters and/or
11 directly on the presentation in the VTK viewer, and/or by using
12 elements of other mesh objects - <b>Standalone group</b> tab of
13 \ref standalone_group "Create group" dialog.</li>
14 <li> by creating a group of elements generated on the chosen
15 geometrical object - <b>Group on geometry</b> tab of \ref
16 creating_groups_page "Create group" dialog and \ref
17 create_groups_from_geometry_page "Create Groups from Geometry"
19 <li> by creating a group of elements satisfying to certain critaria -
20 <b>Group on filter</b> tab of \ref creating_groups_page
21 "Create group" dialog.</li>
22 <li> by creating groups of nodes and elements from the chosen submesh
23 (type of elements depends on dimension of submesh geometry) -
24 using <b>Mesh -> Construct Group</b> menu item (available in contextual
26 <li> by creating groups of entities from existing groups of superior
27 dimensions - using \subpage group_of_underlying_elements_page
28 "Create Group of Underlying Elements" dialog.</li>
32 The created groups can be later:
35 <li>\subpage editing_groups_page "Edited"</li>
36 <li>\subpage using_operations_on_groups_page "Subjected to Boolean operations"</li>
37 <li>\subpage deleting_groups_page "Deleted"</li>

41 groups is \ref selection_filter_library_page.
