void BiCubic2DFiniteElement::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.

void BiCubic2DFiniteElement::CalcHessian | ( | const IntegrationPoint & | ip, |
DenseMatrix & | h | ||
) | const [virtual] |
each row of h contains the upper triangular part of the hessian of one shape function; the order in 2D is {u_xx, u_xy, u_yy}
Reimplemented from FiniteElement.
