Detailed Description

Base class for all 'grouping' entities. The following derived classes are typical:

NodeSet – grouping of nodes (0d topology)

EdgeSet – grouping of edges (1d topology)

FaceSet – grouping of faces (2d topology) [Surface]

Similarly, there is:

NodeBlock – grouping of 'similar' nodes (same degree of freedom, ...)

ElementBlock – grouping of 'similar' elements (same element topology, attributes, ...) 0d, 1d, 2d, 3d topology possible – e.g., sphere, bar, quad, hex

A Region is also a grouping entity, except that its list of subentites are other GroupingEntities. That is, it maintains a list of NodeBlocks, ElementBlocks, NodeLists, CommLists and Surfaces. [Similar to the "Composite Patter" in Design Patterns] All interface to GroupingEntities is through the Region class; clients of the IO subsystem have no direct access to the underlying GroupingEntities (other than the Region).

Each GroupingEntity contains:

– name

– MeshEntities of the specified topological dimension

– Optional attributes, either global (applied to the groupingentity), or unique value(s) to be applied to each subentity.

– Data items
