Detailed Description

template<class M, class I>
struct Dune::CommMatrixRow< M, I >

Utility class for comunicating the matrix entries.

Template Parameters
MThe type of the matrix.
IThe type of the ParallelIndexSet.

Constructor & Destructor Documentation

◆ CommMatrixRow()

template<class M , class I >
Dune::CommMatrixRow< M, I >::CommMatrixRow ( M &  m_,
const Dune::GlobalLookupIndexSet< I > &  idxset_,
const I &  aggidxset_ 
)
inline

Constructor.

Parameters
m_The matrix to communicate the values. That is the local original matrix as the source of the communication and the redistributed at the target of the communication.
idxset_The index set for the original matrix.
aggidxset_The index set for the redistributed matrix.

Member Function Documentation

◆ setOverlapRowsToDirichlet()

template<class M , class I >
void Dune::CommMatrixRow< M, I >::setOverlapRowsToDirichlet ( )
inline

Sets the non-owner rows correctly as Dirichlet boundaries.

This should be called after the communication.
