5 In Mesh module it is possible to create groups of mesh elements:
6 nodes, edges, faces, volumes, 0D elements or balls. One group contains
7 elements of only one type. The following ways of creation are
10 - by selecting the elements using filters and/or directly on the
11 presentation in the VTK viewer, and/or by using elements of other
12 mesh objects - \ref standalone_group "Standalone group"
13 tab of \ref creating_groups_page "Create group" dialog.
14 - by creating a group of elements generated on the chosen geometrical
15 object - \ref group_on_geom "Group on geometry" tab of
16 \subpage creating_groups_page "Create group" dialog and
17 \subpage create_groups_from_geometry_page "Create Groups from Geometry"
19 - by creating a group of elements satisfying to certain criteria -
20 \ref group_on_filter "Group on filter" tab of
21 \subpage creating_groups_page "Create group" dialog.
22 - 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 context
26 - 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.
30 The created groups can be later:
32 - \subpage editing_groups_page "Edited"
33 - \subpage using_operations_on_groups_page "Subjected to Boolean operations"
34 - \subpage deleting_groups_page "Deleted"
36 In the Object Browser, if groups or sub-meshes container item has more
37 than one child sub-object, it is possible to sort the children in
38 ascending order. For this, select the parent object in the Object
39 Browser and choose <b>Sort children</b> context menu item.

43 An important tool, providing filters for creation of \b Standalone
44 groups and groups <b>On Filter</b> is \ref selection_filter_library_page.
