void mfem::RT0TriangleFiniteElement::CalcDivShape ( const IntegrationPoint ip,
Vector divshape 
) const
virtual

This virtual function evaluates the divergence of all shape functions at the given IntegrationPoint. The result is stored in the Vector divshape (of size Dof).

Reimplemented from mfem::FiniteElement.

Definition at line 2446 of file fe.cpp.

void mfem::RT0TriangleFiniteElement::CalcVShape ( const IntegrationPoint ip,
DenseMatrix shape 
) const
virtual

This virtual function evaluates the values of all components of all shape functions at the given IntegrationPoint. The result is stored in the DenseMatrix shape (Dof x Dim) so that each row contains the components of one shape function.

Reimplemented from mfem::FiniteElement.

Definition at line 2433 of file fe.cpp.

virtual void mfem::RT0TriangleFiniteElement::CalcVShape ( ElementTransformation Trans,
DenseMatrix shape 
) const
inlinevirtual

Reimplemented from mfem::FiniteElement.

Definition at line 756 of file fe.hpp.

void mfem::RT0TriangleFiniteElement::GetLocalInterpolation ( ElementTransformation Trans,
DenseMatrix I 
) const
virtual

Return the local interpolation matrix I (Dof x Dof) where the fine element is the image of the base geometry under the given transformation.

Reimplemented from mfem::FiniteElement.

Definition at line 2457 of file fe.cpp.

void mfem::RT0TriangleFiniteElement::Project ( VectorCoefficient vc,
ElementTransformation Trans,
Vector dofs 
) const
virtual

Given a vector coefficient and a transformation, compute its projection (approximation) in the local finite dimensional space in terms of the degrees of freedom. (VectorFiniteElements)

Reimplemented from mfem::FiniteElement.
