◆ AssembleElementMatrix()

virtual void mfem::MixedScalarVectorIntegrator::AssembleElementMatrix	(	const FiniteElement &	fe,
		ElementTransformation &	Trans,
		DenseMatrix &	elmat
	)

inlinevirtual

Support for use in BilinearForm. Can be used only when appropriate.

Appropriate use cases are classes derived from MixedScalarVectorIntegrator where the trial and test spaces can be the same. Examples of such classes are: MixedVectorDivergenceIntegrator, MixedScalarWeakDivergenceIntegrator, etc.

Reimplemented from mfem::BilinearFormIntegrator.

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.
