void mfem::VectorConvectionNLFIntegrator::AddMultMF ( const Vector x,
Vector y 
) const
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::NonlinearFormIntegrator.

Definition at line 37 of file nonlininteg_vectorconvection_mf.cpp.

void mfem::VectorConvectionNLFIntegrator::AddMultPA ( const Vector x,
Vector y

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.
