Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.
This method can be called only after the method AssembleMF() has been called.
Reimplemented from mfem::NonlinearFormIntegrator.
