Detailed Description

Abstract base class for high-order Nedelec spaces on elements with triangular faces.

The Nedelec DoFs on the interior of triangular faces come in pairs which share an interpolation point but have different vector directions. These directions depend on the orientation of the face and can therefore differ in neighboring elements. The mapping required to transform these DoFs can be implemented as series of 2x2 linear transformations. The raw data for these linear transformations is stored in the T_data and TInv_data arrays and can be accessed as DenseMatrices using the GetFaceTransform() and GetFaceInverseTransform() methods.

InvTransformDual()

void mfem::ND_StatelessDofTransformation::InvTransformDual ( const Array< int > &  face_orientation, double *  v  ) const

Inverse Transform dual DoFs

Implements mfem::StatelessDofTransformation.

Definition at line 296 of file doftrans.cpp.

InvTransformPrimal()

void mfem::ND_StatelessDofTransformation::InvTransformPrimal ( const Array< int > &  face_orientation, double *  v  ) const

virtual

Inverse transform local DoFs. Used to transform DoFs from a global vector back to their element-local form. For example, this must be used to transform the vector obtained using GridFunction::GetSubVector before it can be used to compute a local interpolation.

Implements mfem::StatelessDofTransformation.

TransformDual()

void mfem::ND_StatelessDofTransformation::TransformDual ( const Array< int > &  face_orientation, double *  v  ) const

virtual

Transform dual DoFs as computed by a LinearFormIntegrator before summing into a LinearForm object.

Implements mfem::StatelessDofTransformation.

Definition at line 272 of file doftrans.cpp.

TransformPrimal()

void mfem::ND_StatelessDofTransformation::TransformPrimal ( const Array< int > &  face_orientation, double *  v  ) const

virtual

Transform local DoFs to align with the global DoFs. For example, this transformation can be used to map the local vector computed by FiniteElement::Project() to the transformed vector stored within a GridFunction object.

Implements mfem::StatelessDofTransformation.
