Detailed Description

Class for parallel meshes.

Constructor & Destructor Documentation

ParMesh() [1/7]

mfem::ParMesh::ParMesh ( const ParNCMesh &  pncmesh )

protected

Create from a nonconforming mesh.

Definition at line 853 of file pmesh.cpp.

ParMesh() [2/7]

mfem::ParMesh::ParMesh ( )

inline

Default constructor. Create an empty ParMesh.

Definition at line 290 of file pmesh.hpp.

ParMesh() [3/7]

mfem::ParMesh::ParMesh	(	MPI_Comm	comm,
		Mesh &	mesh,
		int *	partitioning_ = NULL,
		int	part_method = 1
	)

Create a parallel mesh by partitioning a serial Mesh.

The mesh is partitioned automatically or using external partitioning data (the optional parameter 'partitioning_[i]' contains the desired MPI rank for element 'i'). Automatic partitioning uses METIS for conforming meshes and quick space-filling curve equipartitioning for nonconforming meshes (elements of nonconforming meshes should ideally be ordered as a sequence of face-neighbors).

Definition at line 107 of file pmesh.cpp.

ParMesh() [4/7]

mfem::ParMesh::ParMesh ( const ParMesh &  pmesh, bool  copy_nodes = true  )

explicit

Copy constructor. Performs a deep copy of (almost) all data, so that the source mesh can be modified (e.g. deleted, refined) without affecting the new mesh. If 'copy_nodes' is false, use a shallow (pointer) copy for the nodes, if present.

Definition at line 31 of file pmesh.cpp.

ParMesh() [5/7]

mfem::ParMesh::ParMesh	(	MPI_Comm	comm,
		std::istream &	input,
		bool	refine = true
	)

Read a parallel mesh, each MPI rank from its own file/stream.

The refine parameter is passed to the method Mesh::Finalize().

Definition at line 924 of file pmesh.cpp.

Finalize()

void mfem::ParMesh::Finalize ( bool  refine = false, bool  fix_orientation = false  )

overridevirtual

Finalize the construction of a general Mesh.

This method will:

• check and optionally fix the orientation of regular elements
• check and fix the orientation of boundary elements
• assume that vertices are defined, if Nodes == NULL
• assume that Nodes are defined, if Nodes != NULL.

  Parameters

  [in]	refine	If true, prepare the Mesh for conforming refinement of triangular or tetrahedral meshes.
  [in]	fix_orientation	If true, fix the orientation of inverted mesh elements by permuting their vertices.

  Before calling this method, call FinalizeTopology() and ensure that the Mesh vertices or nodes are set.

Reimplemented from mfem::Mesh.

FindPoints()

int mfem::ParMesh::FindPoints ( DenseMatrix &  point_mat, Array< int > &  elem_ids, Array< IntegrationPoint > &  ips, bool  warn = true, InverseElementTransformation *  inv_trans = NULL  )

overridevirtual

Find the ids of the elements that contain the given points, and their corresponding reference coordinates.

The DenseMatrix point_mat describes the given points - one point for each column; it should have SpaceDimension() rows.

The InverseElementTransformation object, inv_trans, is used to attempt the element transformation inversion. If NULL pointer is given, the method will use a default constructed InverseElementTransformation. Note that the algorithms in the base class InverseElementTransformation can be completely overwritten by deriving custom classes that override the Transform() method.

If no element is found for the i-th point, elem_ids[i] is set to -1.

In the ParMesh implementation, the point_mat is expected to be the same on all ranks. If the i-th point is found by multiple ranks, only one of them will mark that point as found, i.e. set its elem_ids[i] to a non-negative number; the other ranks will set their elem_ids[i] to -2 to indicate that the point was found but assigned to another rank.

Returns

The total number of points that were found.

Note

This method is not 100 percent reliable, i.e. it is not guaranteed to find a point, even if it lies inside a mesh element.

GetFaceElementTransformations()

overridevirtual

Returns (a pointer to an object containing) the following data:

2) Elem2No - the index of the second element that contains this face this element has outward unit normal vector as the face multiplied with -1;

3) Elem1, Elem2 - pointers to the ElementTransformation's of the first and the second element respectively;

4) Face - pointer to the ElementTransformation of the face;

5) Loc1, Loc2 - IntegrationPointTransformation's mapping the face coordinate system to the element coordinate system (both in their reference elements). Used to transform IntegrationPoints from face to element. More formally, let: TL1, TL2 be the transformations represented by Loc1, Loc2, TE1, TE2 - the transformations represented by Elem1, Elem2, TF - the transformation represented by Face, then TF(x) = TE1(TL1(x)) = TE2(TL2(x)) for all x in the reference face.

6) FaceGeom - the base geometry for the face.

The mask specifies which fields in the structure to return: mask & 1 - Elem1, mask & 2 - Elem2 mask & 4 - Loc1, mask & 8 - Loc2, mask & 16 - Face. These mask values are defined in the ConfigMasks enum type as part of the FaceElementTransformations class in fem/eltrans.hpp.

Note

The returned object is owned by the class and is shared, i.e., calling this function resets pointers obtained from previous calls. Also, the returned object should NOT be deleted by the caller.
