## Member Function Documentation

 void GaussBiLinear2DFiniteElement::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 FiniteElement.

Definition at line 696 of file fe.cpp.

 void GaussBiLinear2DFiniteElement::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 FiniteElement.

Definition at line 685 of file fe.cpp.

 void GaussBiLinear2DFiniteElement::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 FiniteElement.
