Detailed Description

A class for non-conforming AMR. The class is not used directly by the user, rather it is an extension of the Mesh class.

In general, the class is used by MFEM as follows:

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

	)

Load from a stream. The id header is assumed to have been read already from

Parameters

[in]	input	.
[in]	version	is 10 for the v1.0 NC format, or 1 for the legacy v1.1 format.
[out]	curved	is set to 1 if the curvature GridFunction follows after mesh data.
[out]	is_nc	(again treated as a boolean) is set to 0 if the legacy v1.1 format in fact defines a conforming mesh. See Mesh::Loader for details.

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.

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 5042 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 1778 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 4366 of file ncmesh.cpp.

const NCList& mfem::NCMesh::GetEdgeList ( )
