Member Function Documentation

const IntegrationPoint& mfem::ElementTransformation::GetIntPoint ( )

inline

Definition at line 35 of file eltrans.hpp.

virtual int mfem::ElementTransformation::GetSpaceDim ( )

pure virtual

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

Implemented in mfem::IsoparametricTransformation.

virtual const DenseMatrix& mfem::ElementTransformation::Jacobian ( )

pure 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.

Implemented in mfem::IsoparametricTransformation.

virtual int mfem::ElementTransformation::Order ( )

pure virtual

Implemented in mfem::IsoparametricTransformation.

virtual int mfem::ElementTransformation::OrderGrad ( const FiniteElement *  fe )

pure virtual

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

Implemented in mfem::IsoparametricTransformation.

virtual int mfem::ElementTransformation::OrderJ ( )

pure virtual

Implemented in mfem::IsoparametricTransformation.

virtual int mfem::ElementTransformation::OrderW ( )

pure virtual

Implemented in mfem::IsoparametricTransformation.

void mfem::ElementTransformation::SetIntPoint ( const IntegrationPoint *  ip )

inline

Definition at line 33 of file eltrans.hpp.

virtual void mfem::ElementTransformation::Transform ( const IntegrationPoint &  , Vector &    )

pure virtual

Implemented in mfem::IsoparametricTransformation.

virtual void mfem::ElementTransformation::Transform ( const IntegrationRule &  , DenseMatrix &    )

pure virtual

Implemented in mfem::IsoparametricTransformation.

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

pure virtual

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

Implemented in mfem::IsoparametricTransformation.

virtual int mfem::ElementTransformation::TransformBack ( const Vector &  , IntegrationPoint &    )

pure 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.

Implemented in mfem::IsoparametricTransformation.

virtual double mfem::ElementTransformation::Weight ( )

pure virtual

Implemented in mfem::IsoparametricTransformation.
