Detailed Description

template<class M, class X, class Y, class C>
class Dune::OverlappingSchwarzOperator< M, X, Y, C >

An overlapping schwarz operator.

This operator represents a parallel matrix product using sequential data structures together with a parallel index set describing an overlapping domain decomposition and the communication.

Template Parameters
MThe type of the sequential matrix to use, e.g. BCRSMatrix or another matrix type fulfilling the matrix interface of ISTL.
XThe type of the sequential vector to use for the left hand side, e.g. BlockVector or another type fulfilling the ISTL vector interface.
YThe type of the sequential vector to use for the right hand side, e..g. BlockVector or another type fulfilling the ISTL vector interface.
CThe type of the communication object. This must either be OwnerOverlapCopyCommunication or a type implementing the same interface.
