Detailed Description

A class for non-conforming AMR on higher-order hexahedral, quadrilateral or triangular meshes.

The class is used as follows:

  1. NCMesh is constructed from elements of an existing Mesh. The elements are copied and become roots of the refinement hierarchy.
  2. Some elements are refined with the Refine() method. Both isotropic and anisotropic refinements of quads/hexes are supported.
  3. A new Mesh is created from NCMesh containing the leaf elements. This new mesh may have non-conforming (hanging) edges and faces.
  4. FiniteElementSpace asks NCMesh for a list of conforming, master and slave edges/faces and creates the conforming interpolation matrix P.
  5. A continuous/conforming solution is obtained by solving P'*A*P x = P'*b.
  6. Repeat from step 2.

mfem::NCMesh::NCMesh ( const Mesh mesh,

Return all vertex-, edge- and face-neighbors of a single element. You can limit the number of elements being checked using 'search_set'. The complexity of the function is linear in the size of the search set.

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.

void mfem::NCMesh::GetBoundaryClosure ( const Array< int > &  bdr_attr_is_ess,

virtual

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.

Reimplemented in mfem::ParNCMesh.

Definition at line 2933 of file ncmesh.cpp.

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 1356 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().

Definition at line 2813 of file ncmesh.cpp.

Return the current list of conforming and nonconforming edges.

Given an edge (by its vertex indices v1 and v2) return the first (geometric) parent edge that exists in the Mesh or -1 if there is no such parent.

Expand a set of elements by all vertex-, edge- and face-neighbors. The output array 'expanded' will contain all items from 'elements' (provided they are in 'search_set') plus their neighbors. The neighbor search can be limited to the optional search set. The complexity is linear in the sum of the sizes of 'elements' and 'search_set'.

Perform the given batch of refinements. Please note that in the presence of anisotropic splits additional refinements may be necessary to keep the mesh consistent. However, the function always performs at least the requested refinements.

void mfem::NCMesh::Update ( )
protectedvirtual

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. Secondary data includes: leaf_elements, vertex_nodeId, face_list, edge_list, and everything in ParNCMesh.
