Member Function Documentation

DenseMatrix& mfem::IsoparametricTransformation::GetPointMat ( )

inline

Definition at line 80 of file eltrans.hpp.

virtual int mfem::IsoparametricTransformation::GetSpaceDim ( )

inlinevirtual

Get dimension of target space (we support 2D meshes embedded in 3D; in this case the function should return "3").

Implements mfem::ElementTransformation.

Definition at line 96 of file eltrans.hpp.

const DenseMatrix & mfem::IsoparametricTransformation::Jacobian ( )

virtual

Return the Jacobian of the transformation at the IntPoint. The first column contains the x derivatives of the transformation, the second – the y derivatives, etc.

Implements mfem::ElementTransformation.

Definition at line 52 of file eltrans.cpp.

virtual int mfem::IsoparametricTransformation::Order ( )

inlinevirtual

Implements mfem::ElementTransformation.

Definition at line 91 of file eltrans.hpp.

int mfem::IsoparametricTransformation::OrderGrad ( const FiniteElement *  fe )

virtual

order of adj(J)^t.grad(fi)

Implements mfem::ElementTransformation.

Definition at line 110 of file eltrans.cpp.

int mfem::IsoparametricTransformation::OrderJ ( )

virtual

Implements mfem::ElementTransformation.

Definition at line 82 of file eltrans.cpp.

int mfem::IsoparametricTransformation::OrderW ( )

virtual

Implements mfem::ElementTransformation.

void mfem::IsoparametricTransformation::Transform ( const IntegrationRule &  ir, DenseMatrix &  tr  )

virtual

Implements mfem::ElementTransformation.

Definition at line 139 of file eltrans.cpp.

void mfem::IsoparametricTransformation::Transform ( const DenseMatrix &  matrix, DenseMatrix &  result  )

virtual

Transform columns of 'matrix', store result in 'result'.

Implements mfem::ElementTransformation.

Definition at line 165 of file eltrans.cpp.

int mfem::IsoparametricTransformation::TransformBack ( const Vector &  , IntegrationPoint &    )

virtual

Attempt to find the IntegrationPoint that is transformed into the given point in physical space. If the invesion fails a non-zero value is returned. This method is not 100 percent reliable for non-linear transformations.

Implements mfem::ElementTransformation.

Definition at line 190 of file eltrans.cpp.

double mfem::IsoparametricTransformation::Weight ( )

virtual

Implements mfem::ElementTransformation.
