-************************************
-Group Based on Nodes of Other Groups
-************************************
-
-
-To create a standalone group of entities basing on nodes of existing reference groups, in the **Mesh** menu select **Group of underlying entities**.
-
-The following dialog box will appear:
-
-.. image:: ../images/dimgroup_dlg.png
- :align: center
-
-In this dialog box specify
-
- * the resulting **Group name**,
- * the **Elements Type** of entities of the resulting group,
- * the criterion of inclusion of a mesh entity to the result group, which is **Number of common nodes** of the entity and the reference groups:
- * **All** - include if all nodes are common;
- * **Main** - include if all corner nodes are common (meaningful for a quadratic mesh)
- * **At least one** - include if one or more nodes are common
- * **Majority** - include if half or more nodes are common
-
- * select reference groups,
- * If **Include underlying entities only** option is activated an entity can be included if it is based on nodes of one element of a reference group.

-In the figure below, there are two reference Volume groups:
-
-.. image:: ../images/dimgroup_src.png
- :align: center
-
-.. centered::
- Reference groups
-
-In this case the following results for Faces, Edges and Nodes are obtained:
-
-.. image:: ../images/dimgroup_2d.png
- :align: center
-
-.. centered::
- Faces
-
-.. image:: ../images/dimgroup_1d.png
- :align: center
-
-.. centered::
- Edges
-
-.. image:: ../images/dimgroup_0d.png
- :align: center
-
-.. centered::
- Nodes
