Detailed Description
template<class M, class I>
struct Dune::CommMatrixRow< M, I >
struct Dune::CommMatrixRow< M, I >
Utility class for comunicating the matrix entries.
- Template Parameters
-
M The type of the matrix. I The type of the ParallelIndexSet.
Constructor & Destructor Documentation
◆ CommMatrixRow()
template<class M , class I >

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 >
|
inline |
Sets the non-owner rows correctly as Dirichlet boundaries.
This should be called after the communication.
