Member Function Documentation

void Linear3DFiniteElement::CalcDShape	(	const IntegrationPoint &	ip,
		DenseMatrix &	dshape
	)		const [virtual]

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) (4 x 3) so that each row contains the derivatives of one shape function

Implements FiniteElement.

Definition at line 1909 of file fe.cpp.

References DenseMatrix::Height().

void Linear3DFiniteElement::CalcShape	(	const IntegrationPoint &	ip,
		Vector &	shape
	)		const [virtual]

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 (4)

Implements FiniteElement.

void Linear3DFiniteElement::GetFaceDofs	(	int	face,
		int **	dofs,
		int *	ndofs
	)		const [virtual]

Reimplemented from FiniteElement.

Definition at line 1929 of file fe.cpp.

virtual void Linear3DFiniteElement::ProjectDelta	(	int	vertex,
		Vector &	dofs
	)		const [inline, virtual]

Compute a representation (up to multiplicative constant) for the delta function at the vertex with the given index.

Reimplemented from FiniteElement.
