Detailed Description

Integrator for (Q div u, p) where u=(v1,...,vn) and all vi are in the same scalar FE space; p is also in a (different) scalar FE space.

void VectorDivergenceIntegrator::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 BilinearFormIntegrator.
