Detailed Description

template<class ForeignOverlap>
class Opm::Linear::GlobalIndices< ForeignOverlap >

This class maps domestic row indices to and from "global" indices which is used to construct an algebraic overlap for the parallel linear solvers.

Member Function Documentation

numDomestic()

template<class ForeignOverlap>

size_t Opm::Linear::GlobalIndices< ForeignOverlap >::numDomestic ( ) const

inline

Returns the number domestic indices.

The domestic indices are defined as the process' local indices plus its copies of indices in the overlap regions
