void mfem::ConvectionIntegrator::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::BilinearFormIntegrator.

Definition at line 54 of file bilininteg_convection_mf.cpp.

void mfem::ConvectionIntegrator::AddMultPA ( const Vector x,
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.

void mfem::ConvectionIntegrator::AssembleDiagonalPA ( Vector diag)
virtual

Assemble diagonal and add it to Vector diag.

void mfem::ConvectionIntegrator::AssembleEA ( const FiniteElementSpace fes,
Vector emat,

Method defining element assembly.

The result of the element assembly is added to the emat Vector if add is true. Otherwise, if add is false, we set emat.

Reimplemented from mfem::BilinearFormIntegrator.

void mfem::ConvectionIntegrator::AssembleMF ( const FiniteElementSpace fes)
virtual

Method defining matrix-free assembly.

Used with BilinearFormIntegrators that have different spaces.The result of fully matrix-free assembly is stored internally so that it can be used later in the methods AddMultMF() and AddMultTransposeMF().

Reimplemented from mfem::BilinearFormIntegrator.

Definition at line 22 of file bilininteg_convection_mf.cpp.

void mfem::ConvectionIntegrator::AssemblePA ( const FiniteElementSpace fes)
