Detailed Description

This base class provides a minimal set of interfaces for satisfying user requests for.

• variables that contribute degrees of freedom to this map
• distribution of degrees of freedom among ranks in parallel (e.g. MPI) simulations
• degrees of freedom associated with nodes and elements This minimal set of interfaces is sufficient for providing information for use cases such as building field splits for advanced preconditioning techniques

Sub-classes of this base class may not be fully-featured stand-alone degree of freedom maps. For instance a sub-class may not be constructible without information from an already constructed fully-featured degree of freedom map. As an example, a degree of freedom map for a statically condensed system of equations will require a priori and flow naturally from a degree of freedom map for the full non-condensed system. In this example, the partitioning of the statically condensed degrees of freedom may logically follow the partitioning in the global system, e.g. a face degree of freedom in the global system that is assigned to process i by the full degree of freedom map will retain its rank assignment in the statically condensed degree of freedom map. Because the statically condensed dof map can lazily use the information from the full dof map, it does not require its own partitioning capabilities. Consequently, partitioning interfaces are not present in this base interface
