inlinestatic

Once degrees of freedom have been distributed on all cells, we may want to eliminate duplicates, and enumerate the remaining ones consecutively. This particular function is responsible for the latter part.

This function stores the new indices of all DoFs in ascending order in new_dof_indices, which can be used to renumber all DoFs with the renumber_dofs() function later.

This vector will contain enumerated indices, skipping invalid indices previously stored in it. Additionally, if a all_constrained_indices parameter is provided, DoF identity relations will be considered as well during the enumeration process by identifying similar DoFs on vertices, lines and quads.

Returns the final number of degrees of freedom, which is the number of all valid DoF indices in new_dof_indices.

inlinestatic

Once degrees of freedom have been distributed on all cells, see if we can identify DoFs on neighboring cells. This function does nothing unless the DoFHandler has hp-capabilities.

Return the final number of degrees of freedom, which is the old one minus however many were identified.

template<int dim, int spacedim>

static void internal::DoFHandlerImplementation::Policy::Implementation::merge_invalid_dof_indices_on_ghost_interfaces ( DoFHandler< dim, spacedim > &  dof_handler )

inlinestatic

After DoF unification in Phase 2, we may still have invalid DoF indices left on ghost interfaces that are dominated by a FiniteElement object of an adjacent cell, which could be either a ghost cell or locally owned, whose DoF indices we did not know at the moment of unification. After the first ghost exchange in Phase 5, we know the indices of all dominating DoFs, and we have to assign those invalid entries to their corresponding global value.

This function does nothing unless the DoFHandler has hp- capabilities.

distribute_dofs()

template<int dim, int spacedim>

inlinestatic

During DoF distribution, DoFs on ghost interfaces get different indices assigned by each adjacent subdomain. We need to clarify ownership of those DoFs by imposing a criterion, which is that the adjacent subdomain belonging to the processor of lowest rank prescribes its index.

Thus, we have to invalidate all those DoFs on ghost cells that belong to processors of lower rank than the current one, which is the subdomain_id parameter. Later during ghost exchange in Phase 5, these values will be overwritten by the correct one. The invalidated indices will be stored in the renumbering parameter.

Implementation of DoFHandler::renumber_dofs()

If the second argument has any elements set, elements of the then the vector of new numbers do not relate to the old DoF number but instead to the index of the old DoF number within the set of locally owned DoFs.

(The IndexSet argument is not used in 1d because we only need it for parallel meshes and 1d doesn't support that right now.)
