Detailed Description

A trace face interpolator class for interpolating the normal component of the domain space, e.g. vector \(H^1\), into the range space, e.g. the trace of \(H(div)\) which uses FiniteElement::INTEGRAL map type.

void mfem::NormalInterpolator::AssembleElementMatrix2	(	const FiniteElement &	trial_fe,
		const FiniteElement &	test_fe,
		ElementTransformation &	Trans,
		DenseMatrix &	elmat )

virtual

Compute the local matrix representation of a bilinear form \(a(u,v)\) defined on different trial (given by \(u\)) and test (given by \(v\)) spaces. The rows in the local matrix correspond to the test dofs and the columns – to the trial dofs.

Reimplemented from mfem::BilinearFormIntegrator.
