Detailed Description

Subdomain representation of a topological parent in another ParMesh.

ParSubMesh is a subdomain representation of a ParMesh defined on its parents attributes. The current implementation creates either a domain or surface subset of the parent Mesh and reuses the parallel distribution.

The attributes are taken from the parent. That means if a volume is extracted from a volume, it has the same domain attribute as the parent. Its boundary attributes are generated (there will be one boundary attribute 1 for all of the boundaries).

If a surface is extracted from a volume, the boundary attribute from the parent is assigned to be the new domain attribute. Its boundary attributes are generated (there will be one boundary attribute 1 for all of the boundaries).

For more customized boundary attributes, the resulting ParSubMesh has to be postprocessed.

ParSubMesh maintains the parallel distribution of the elements on corresponding processors.
