Detailed Description

template<class X, class C>
class Dune::OverlappingSchwarzScalarProduct< X, C >

Scalar product for overlapping schwarz methods.

Consistent vectors in interior and border are assumed.

Template Parameters

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.
C	The type of the communication object. This must either be OwnerOverlapCopyCommunication or a type implementing the same interface.

Member Typedef Documentation

communication_type

template<class X , class C >

typedef C Dune::OverlappingSchwarzScalarProduct< X, C >::communication_type

The type of the communication object.

This must either be OwnerOverlapCopyCommunication or a type implementing the same interface.

domain_type

template<class X , class C >

typedef X Dune::OverlappingSchwarzScalarProduct< X, C >::domain_type

The type of the vector to compute the scalar product on.

E.g. BlockVector or another type fulfilling the ISTL vector interface.

Constructor & Destructor Documentation

OverlappingSchwarzScalarProduct()

template<class X , class C >

Dune::OverlappingSchwarzScalarProduct< X, C >::OverlappingSchwarzScalarProduct ( const communication_type &  com )

inline

Constructor needs to know the grid.

Parameters

com	The communication object for syncing overlap and copy data points. (E.~g. OwnerOverlapCopyCommunication )
