Member Function Documentation

void LagrangeHexFiniteElement::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 LagrangeHexFiniteElement::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.
