Detailed Description

The VDofTransformation class implements a nested transformation where an arbitrary DofTransformation is replicated with a vdim >= 1.

Definition at line 139 of file doftrans.hpp.

Constructor & Destructor Documentation

VDofTransformation() [1/2]

mfem::VDofTransformation::VDofTransformation ( int  vdim = 1, int  ordering = 0  )

inline

Default constructor which requires that SetDofTransformation be called before use.

Definition at line 149 of file doftrans.hpp.

VDofTransformation() [2/2]

mfem::VDofTransformation::VDofTransformation ( DofTransformation &  doftrans, int  vdim = 1, int  ordering = 0  )

inline

Constructor with a known DofTransformation.

Definition at line 155 of file doftrans.hpp.

Member Function Documentation

GetDofTransformation()

DofTransformation* mfem::VDofTransformation::GetDofTransformation ( ) const

inline

Return the nested DofTransformation object.

Definition at line 182 of file doftrans.hpp.

GetVDim()

int mfem::VDofTransformation::GetVDim ( ) const

inline

Return the current vdim value.

Definition at line 172 of file doftrans.hpp.

InvTransformDual() [1/3]

virtual void mfem::DofTransformation::InvTransformDual

Inverse Transform dual DoFs

InvTransformDual() [2/3]

void mfem::DofTransformation::InvTransformDual

Definition at line 88 of file doftrans.cpp.

InvTransformDual() [3/3]

void mfem::VDofTransformation::InvTransformDual ( double *  v ) const

virtual

Inverse Transform dual DoFs

Implements mfem::DofTransformation.

Definition at line 203 of file doftrans.cpp.

InvTransformPrimal() [1/3]

virtual void mfem::DofTransformation::InvTransformPrimal

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.

InvTransformPrimal() [2/3]

void mfem::DofTransformation::InvTransformPrimal

Definition at line 60 of file doftrans.cpp.

InvTransformPrimal() [3/3]

void mfem::VDofTransformation::InvTransformPrimal ( 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::DofTransformation.

Definition at line 145 of file doftrans.cpp.

SetDofTransformation()

void mfem::VDofTransformation::SetDofTransformation ( DofTransformation &  doftrans )

inline

Set or change the nested DofTransformation object.

Definition at line 175 of file doftrans.hpp.

SetFaceOrientation()

void mfem::VDofTransformation::SetFaceOrientation ( const Array< int > &  face_orientation )

inline

Definition at line 184 of file doftrans.hpp.

SetVDim()

void mfem::VDofTransformation::SetVDim ( int  vdim )

inline

Set or change the vdim parameter.

Definition at line 162 of file doftrans.hpp.

TransformDual() [1/4]

void mfem::DofTransformation::TransformDual

Transform a matrix of dual DoFs entries as computed by a BilinearFormIntegrator before summing into a BilinearForm object.

Definition at line 35 of file doftrans.cpp.

TransformDual() [2/4]

void mfem::DofTransformation::TransformDual

Definition at line 30 of file doftrans.cpp.

TransformDual() [3/4]

virtual void mfem::DofTransformation::TransformDual

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

TransformDual() [4/4]

void mfem::VDofTransformation::TransformDual ( double *  v ) const

virtual

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

Implements mfem::DofTransformation.

Definition at line 174 of file doftrans.cpp.

TransformPrimal() [1/3]

virtual void mfem::DofTransformation::TransformPrimal

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.

TransformPrimal() [2/3]

void mfem::DofTransformation::TransformPrimal

Definition at line 17 of file doftrans.cpp.

TransformPrimal() [3/3]

void mfem::VDofTransformation::TransformPrimal ( 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::DofTransformation.
