DofMap

class dolfin.cpp.fem.DofMap(*args)

Bases: dolfin.cpp.fem.GenericDofMap

This class handles the mapping of degrees of freedom. It builds a dof map based on a ufc::dofmap on a specific mesh. It will reorder the dofs when running in parallel. Sub-dofmaps, both views and copies, are supported.
