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
|
||
|
|
|
||
|
