Detailed Description

A SubMesh is a mesh defined as a subset of a given mesh. It provides a convenient way to create matching meshes for multiphysics applications by creating meshes for subdomains as subsets of a single global mesh. A mapping from the vertices of the sub mesh to the vertices of the parent mesh is stored as the mesh data named "parent_vertex_indices".
