◆ 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>
Get the parameters describing the behaviuour of AMG.
The returned object can be adjusted to ones needs and then can be reset using setParameters.
- Returns
- The object holding the parameters of AMG.
◆ result()
Return access to result data.
◆ setParameters()
template<class GO , int s, template< class, class, class, int > class Preconditioner, template< class > class Solver>
set AMG parameters
- 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.
