Public Member Functions

field_type dot (const X &x, const X &y) const override
 Dot product of two vectors. It is assumed that the vectors are consistent on the interior+border partition.
 
real_type norm (const X &x) const override
 Norm of a right-hand side vector. The vector must be consistent on the interior+border partition.
 
SolverCategory::Category category () const override
 Category of the scalar product (see SolverCategory::Category)
 

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
XThe type of the sequential vector to use for the left 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.

Member Typedef Documentation

◆ communication_type

template<class X , class C >
typedef C Dune::ParallelScalarProduct< X, C >::communication_type
inherited

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::ParallelScalarProduct< X, C >::domain_type
inherited

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

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