Member Function Documentation

void RT1HexFiniteElement::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 FiniteElement.

void RT1HexFiniteElement::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 FiniteElement.

void RT1HexFiniteElement::Project ( VectorCoefficient vc,

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)
