In Mesh module it is possible to create groups of mesh elements:
|
|
nodes, edges, faces, volumes, 0D elements or balls. 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 - \ref standalone_group "Standalone group"
|
|
tab of \ref creating_groups_page "Create group" dialog.
|
|
- by creating a group of elements generated on the chosen geometrical
|
|
object - \ref group_on_geom "Group on geometry" tab of
|
|
\subpage creating_groups_page "Create group" dialog and
|
|
\subpage create_groups_from_geometry_page "Create Groups from Geometry"
|
|
dialog.
|
|
- by creating a group of elements satisfying to certain criteria -
|
|
\ref group_on_filter "Group on filter" tab of
|
|
\subpage creating_groups_page "Create group" dialog.
|
|
- by creating groups of nodes and elements from the chosen submesh
|
|
(type of elements depends on dimension of submesh geometry) -
|
|
using <b>Mesh -> Construct Group</b> menu item (available in context
|
|
menu as well).
|
|
- by creating groups of entities from existing groups of superior
|
|
dimensions - using \subpage group_of_underlying_elements_page
|
|
"Create Group of Underlying Elements" dialog.
|
|
|
|
The created groups can be later:
|
|
|
|
- \subpage editing_groups_page "Edited"
|
|
- \subpage using_operations_on_groups_page "Subjected to Boolean operations"
|
|
- \subpage deleting_groups_page "Deleted"
|
|
|
|
In the Object Browser, if groups or sub-meshes container item has more
|
|
than one child sub-object, it is possible to sort the children in
|
|
ascending order. For this, select the parent object in the Object
|
|
Browser and choose <b>Sort children</b> context menu item.

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