Detailed Description

Class representing the storage layout of a FaceQuadratureFunction.

FaceQuadratureSpace is defined on either the interior or boundary faces of a mesh, depending on the provided FaceType.

Definition at line 150 of file qspace.hpp.

Constructor & Destructor Documentation

FaceQuadratureSpace() [1/2]

mfem::FaceQuadratureSpace::FaceQuadratureSpace	(	Mesh &	mesh_,
		int	order_,
		FaceType	face_type_
	)

Create a FaceQuadratureSpace based on the global rules from IntRules.

Definition at line 97 of file qspace.cpp.

FaceQuadratureSpace() [2/2]

mfem::FaceQuadratureSpace::FaceQuadratureSpace	(	Mesh &	mesh_,
		const IntegrationRule &	ir,

Member Function Documentation

GetEntityIndex()

int mfem::FaceQuadratureSpace::GetEntityIndex ( const ElementTransformation &  T ) const

overridevirtual

Returns the index associated with the face described by T.

The index may differ from the mesh face or boundary element index depending on the FaceType used to construct the FaceQuadratureSpace.

Implements mfem::QuadratureSpaceBase.

Definition at line 165 of file qspace.cpp.

GetFaceIntRule()

const IntegrationRule& mfem::FaceQuadratureSpace::GetFaceIntRule ( int  idx ) const

inline

Get the IntegrationRule associated with mesh element idx.

Definition at line 188 of file qspace.hpp.

GetFaceType()

FaceType mfem::FaceQuadratureSpace::GetFaceType ( ) const

inline

Returns the face type (boundary or interior).

Definition at line 177 of file qspace.hpp.

GetGeometry()

Geometry::Type mfem::FaceQuadratureSpace::GetGeometry ( int  idx ) const

inlineoverridevirtual

Returns the geometry type of face idx.

Implements mfem::QuadratureSpaceBase.

Definition at line 184 of file qspace.hpp.

GetNumFaces()

int mfem::FaceQuadratureSpace::GetNumFaces ( ) const

inline

Returns number of faces in the mesh.

Definition at line 174 of file qspace.hpp.

GetPermutedIndex()

int mfem::FaceQuadratureSpace::GetPermutedIndex ( int  idx, int  iq  ) const

overridevirtual

Returns the permuted index of the iq quadrature point in entity idx.

For tensor-product faces, returns the lexicographic index of the quadrature point, oriented relative to "element 1".

Implements mfem::QuadratureSpaceBase.

Definition at line 148 of file qspace.cpp.

GetTransformation()

ElementTransformation* mfem::FaceQuadratureSpace::GetTransformation ( int  idx )

inlineoverridevirtual

Returns the face transformation of face idx.

Implements mfem::QuadratureSpaceBase.

Definition at line 180 of file qspace.hpp.

Save()

void mfem::FaceQuadratureSpace::Save ( std::ostream &  out ) const

overridevirtual

Write the FaceQuadratureSpace to the stream out.

Implements mfem::QuadratureSpaceBase.

Definition at line 180 of file qspace.cpp.
