Detailed Description

Integrator for (Q grad u, grad v) = sum_i (Q grad u_i, grad v_i) e_i e_i^T for FE spaces defined by 'dim' copies of a scalar FE space. Where e_i is the unit vector in the i-th direction. The resulting local element matrix is a block-diagonal matrix consisting of 'dim' copies of a scalar diffusion matrix in each diagonal block.

		Vector &	y
	)		const

virtual

Method for partially assembled action.

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 AssemblePA() has been called.

Reimplemented from mfem::BilinearFormIntegrator.

void mfem::VectorDiffusionIntegrator::AssembleDiagonalPA ( Vector & diag )

virtual
