Member Function Documentation

void mfem::Quad2DFiniteElement::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) (6 x 2) so that each row contains the derivatives of one shape function

Implements mfem::FiniteElement.

Definition at line 1035 of file fe.cpp.

void mfem::Quad2DFiniteElement::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 mfem::FiniteElement.

Definition at line 1059 of file fe.cpp.

void mfem::Quad2DFiniteElement::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 (6)

Implements mfem::FiniteElement.

Definition at line 1021 of file fe.cpp.

void mfem::Quad2DFiniteElement::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 mfem::FiniteElement.
