Detailed Description

Class for constructing the (local) discrete divergence matrix which can be used as an integrator in a DiscreteLinearOperator object to assemble the global discrete divergence matrix.

Note: Since the dofs in the L2_FECollection are nodal values, the local discrete divergence matrix (with an RT-type domain space) will depend on the transformation. On the other hand, the local matrix returned by VectorFEDivergenceInterpolator is independent of the transformation.

virtual void DivergenceInterpolator::AssembleElementMatrix2	(	const FiniteElement &	trial_fe,
		const FiniteElement &	test_fe,
		ElementTransformation &	Trans,
		DenseMatrix &	elmat
	)		[inline, 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.
