Detailed Description
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
-
M The type of the sequential matrix to use, e.g. BCRSMatrix or another matrix type fulfilling the matrix interface of ISTL. X The type of the sequential vector to use for the left hand side, e.g. BlockVector or another type fulfilling the ISTL vector interface. Y The type of the sequential vector to use for the right hand side, e..g. BlockVector or another type fulfilling the ISTL vector interface. C The type of the communication object. This must either be OwnerOverlapCopyCommunication or a type implementing the same interface.
