Definition at line 251 of file fe.hpp.

anonymous enum

Enumeration for MapType: defines how reference functions are mapped to physical space.

A reference function, uh(xh), can be mapped to a function, u(x), on a general physical element in following ways:

VALUE       u(x) = uh(xh)
INTEGRAL    u(x) = (1/w) * uh(xh)
H_DIV       u(x) = (J/w) * uh(xh)
H_CURL      u(x) = J^{-t} * uh(xh)           (square J)
H_CURL      u(x) = J*(J^t*J)^{-1} * uh(xh)   (general J)

where

x = T(xh) is the image of the reference point xh ("x hat"),
J = J(xh) is the Jacobian matrix of the transformation T, and
w = w(xh) = / det(J),           for square J,
            \ det(J^t*J)^{1/2}, for general J,
          is the transformation weight factor.

Enumerator
VALUE	For scalar fields; preserves point values.
INTEGRAL	For scalar fields; preserves volume integrals.
H_DIV	For vector fields; preserves surface integrals of the normal component
H_CURL	For vector fields; preserves line integrals of the tangential component

void mfem::FiniteElement::GetTransferMatrix	(	const FiniteElement &	fe,
		ElementTransformation &	Trans,
		DenseMatrix &	I
	)		const

virtual

Return interpolation matrix, I, which maps dofs from a coarse element, fe, to the fine dofs on this finite element.

Trans represents the mapping from the reference element of this element into a subset of the reference space of the element fe, thus allowing the "coarse" FiniteElement to be different from the "fine" FiniteElement as when h-refinement is combined with p-refinement or p-derefinement. It is assumed that both finite elements use the same MapType.
