Member Function Documentation

AddMultMF()

virtual 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.

AddMultPA()

virtual void mfem::VectorConvectionNLFIntegrator::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.

Reimplemented from mfem::NonlinearFormIntegrator.

AssembleElementGrad()

void mfem::VectorConvectionNLFIntegrator::AssembleElementGrad ( const FiniteElement & el, ElementTransformation & Tr, const Vector & elfun, DenseMatrix & elmat )

virtual

Assemble the local gradient matrix.

Reimplemented from mfem::NonlinearFormIntegrator.

Reimplemented in mfem::ConvectiveVectorConvectionNLFIntegrator, and mfem::SkewSymmetricVectorConvectionNLFIntegrator.

Definition at line 779 of file nonlininteg.cpp.

AssembleElementVector()

void mfem::VectorConvectionNLFIntegrator::AssembleElementVector ( const FiniteElement & el, ElementTransformation & Tr, const Vector & elfun, Vector & elvect )

virtual

Perform the local action of the NonlinearFormIntegrator.

Reimplemented from mfem::NonlinearFormIntegrator.

Definition at line 742 of file nonlininteg.cpp.

AssembleMF()

virtual void mfem::VectorConvectionNLFIntegrator::AssembleMF ( const FiniteElementSpace & fes )

virtual

Method defining fully unassembled operator.

Reimplemented from mfem::NonlinearFormIntegrator.

AssemblePA() [1/2]

virtual void mfem::VectorConvectionNLFIntegrator::AssemblePA ( const FiniteElementSpace & fes )

virtual

Method defining partial assembly.

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultPA().

Reimplemented from mfem::NonlinearFormIntegrator.

AssemblePA() [2/2]

void mfem::NonlinearFormIntegrator::AssemblePA ( const FiniteElementSpace & trial_fes, const FiniteElementSpace & test_fes )

virtual

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultPA(). Used with BilinearFormIntegrators that have different spaces.

Reimplemented from mfem::NonlinearFormIntegrator.
