Detailed Description

ParTransferMap represents a mapping of degrees of freedom from a source ParGridFunction to a destination ParGridFunction.

This map can be constructed from a parent ParMesh to a ParSubMesh or vice versa. Additionally one can create it between two ParSubMeshes that share the same root parent. In this case, a supplemental ParFiniteElementSpace is created on the root parent ParMesh to transfer degrees of freedom.
