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 VectorFEDivergenceIntegrator is independent of the transformation.

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

inlinevirtual

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.
