◆ getReuse()
template<class GO , int s, template< class, class, class, int > class Preconditioner, template< class > class Solver>
Return whether the AMG is reused during call to apply()
◆ norm()
template<class GO , int s, template< class, class, class, int > class Preconditioner, template< class > class Solver>
compute global norm of a vector
- Parameters
-
◆ parameters()
template<class GO , int s, template< class, class, class, int > class Preconditioner, template< class > class Solver>

- Parameters
-
[in] | params_ | a parameter object of Type Dune::Amg::Parameters |
◆ setReuse()
template<class GO , int s, template< class, class, class, int > class Preconditioner, template< class > class Solver>
Set whether the AMG should be reused again during call to apply().
◆ statistics()
template<class GO , int s, template< class, class, class, int > class Preconditioner, template< class > class Solver>
Get statistics of the AMG solver (no of levels, timings).
- Returns
- statistis of the AMG solver.
