Detailed Description

Class for integrating the bilinear form a(u,v) := (Q u, v), where u=(u1,...,un) and v=(v1,...,vn); ui and vi are defined by scalar FE through standard transformation.

inline

Construct an integrator with scalar coefficient q. If possible, save memory by using a scalar integrator since the resulting matrix is block diagonal with the same diagonal block repeated.

void mfem::VectorMassIntegrator::AddMultMF	(	const Vector &	x,
		Vector &	y

virtual

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::BilinearFormIntegrator.
