Member Function Documentation

void mfem::L2_TriangleElement::CalcDShape ( const IntegrationPoint ip,
DenseMatrix dshape 
) const
virtual

pure virtual function which evaluates the values of all partial derivatives of all shape functions at a given point ip and stores them in the matrix dshape (Dof x Dim) so that each row contains the derivatives of one shape function

Implements mfem::FiniteElement.

Definition at line 8815 of file fe.cpp.

void mfem::L2_TriangleElement::CalcShape ( const IntegrationPoint ip,
Vector shape 
) const
virtual

pure virtual function which evaluates the values of all shape functions at a given point ip and stores them in the vector shape of dimension Dof

Implements mfem::FiniteElement.

Definition at line 8793 of file fe.cpp.

virtual void mfem::L2_TriangleElement::ProjectCurl ( const FiniteElement fe,
ElementTransformation Trans,
DenseMatrix curl 
) const
inlinevirtual

Compute the discrete curl matrix from the given FiniteElement onto 'this' FiniteElement. The ElementTransformation is included to support cases when the matrix depends on it.

Reimplemented from mfem::FiniteElement.

Definition at line 1635 of file fe.hpp.

void mfem::L2_TriangleElement::ProjectDelta ( int  vertex,
Vector dofs 
) const
virtual

Compute a representation (up to multiplicative constant) for the delta function at the vertex with the given index.

Reimplemented from mfem::FiniteElement.
