To create a standalone group of entities basing on nodes of existing reference groups, in the Mesh menu select Group based on nodes of other groups.

The following dialog box will appear:

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:
