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.

Constructor & Destructor Documentation

mfem::VectorMassIntegrator::VectorMassIntegrator ( )
inline

Construct an integrator with coefficient 1.0.

Definition at line 2159 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( Coefficient q,
int  qo = 0 
)
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.

const IntegrationRule ir 
)
inline

Definition at line 2166 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( VectorCoefficient q,
int  qo = 0

inline

Construct an integrator with diagonal coefficient q.

Definition at line 2170 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( MatrixCoefficient q,

Member Function Documentation

void mfem::VectorMassIntegrator::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 46 of file bilininteg_vecmass_mf.cpp.

void mfem::VectorMassIntegrator::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.

void mfem::VectorMassIntegrator::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().
