Return all vertex-, edge- and face-neighbors of a set of elements. The neighbors are returned as a list (neighbors != NULL), as a set (neighbor_set != NULL), or both. The sizes of the set arrays must match that of leaf_elements. The function is intended to be used for large sets of elements and its complexity is linear in the number of leaf elements in the mesh.

Get a list of vertices (2D/3D) and edges (3D) that coincide with boundary elements with the specified attributes (marked in 'bdr_attr_is_ess'). In 3D this function also reveals "hidden" boundary edges. In parallel it helps identifying boundary vertices/edges affected by non-local boundary elements.

const Table & mfem::NCMesh::GetDerefinementTable | ( | ) |
Return a list of derefinement opportunities. Each row of the table contains Mesh indices of existing elements that can be derefined to form a single new coarse element. Row numbers are then passed to Derefine. This function works both in serial and parallel.
Definition at line 1421 of file ncmesh.cpp.
const CoarseFineTransformations & mfem::NCMesh::GetDerefinementTransforms | ( | ) |
After derefinement, calculate the relations of previous fine elements (some of which may no longer exist) to the current leaf elements. Unlike for refinement, Derefine() may only be called once before this function so there is no MarkFineLevel().

Apart from the primary data structure, which is the element/node/face hierarchy, there is secondary data that is derived from the primary data and needs to be updated when the primary data changes. Update() takes care of that and needs to be called after refinement and derefinement.
Reimplemented in mfem::ParNCMesh.
