Member Function Documentation

createParallelIndexSet()

template<class LinearSolverTraits >

template<class Comm >

void Dumux::ParallelISTLHelper< LinearSolverTraits >::createParallelIndexSet ( Comm &  comm ) const

inline

Creates a parallel index set for a communicator.

Parameters

comm	The OwnerOverlapCopyCommunication communicators

The parallel index set contains for each dof index, the triplet (globalIndex, (localIndex, attribute)) where attribute is owner, overlap or copy. Each dof is uniquely owned by exactly one process. This allows to apply local operators additively to get a global operator without communication.

dofMapper()

template<class LinearSolverTraits >

const DofMapper & Dumux::ParallelISTLHelper< LinearSolverTraits >::dofMapper ( ) const

inline

Return the dofMapper.

gridView()

template<class LinearSolverTraits >

const GridView & Dumux::ParallelISTLHelper< LinearSolverTraits >::gridView ( ) const

inline

Return the gridView.

isGhost()

template<class LinearSolverTraits >

bool Dumux::ParallelISTLHelper< LinearSolverTraits >::isGhost ( std::size_t  i ) const

inline

isOwned()

template<class LinearSolverTraits >

bool Dumux::ParallelISTLHelper< LinearSolverTraits >::isOwned ( std::size_t  i ) const

inline
