std::shared_ptr< SolverType >  smoother_post,
std::shared_ptr< SolverType >  smoother_peak,
std::shared_ptr< SolverType >  coarse_solver = nullptr 
)
inline

Pushes a standard refined level into the hierarchy.

Parameters
[in]system_matrixA reference to the system matrix.
[in]system_filterA reference to the system filter.
[in]transfer_operatorA reference to the transfer operator onto this level.
[in]smoother_preA shared pointer to the pre-smoother. May be nullptr if no pre-smoother is to be used.
[in]smoother_postA shared pointer to the post-smoother. May be nullptr if no post-smoother is to be used.
[in]smoother_peakA shared pointer to the peak-smoother. Is set to nullptr, the multigrid will use both the pre- and post-smoothers as the peak-smoother.
[in]coarse_solverA shared pointer to the coarse grid solver. This one is usually nullptr, unless one wants to use this refined level also as a coarse-grid level.
Note
The smoother_pre, smoother_post, smoother_peak and coarse_solver pointers need not point to different objects. This class will ensure the correct handling of unique solver objects independent of whether more that one pointer references the same unique object on one level.
