A structure containing boost::signal objects for optional processing in multigrid solvers.
Each of these signals is called twice, once before and once after the action is performed. The two function calls differ in the boolean argument before
, which is true the first time and false the second.

boost::signals2::signal<void(const bool before)> mg::Signals::transfer_to_mg |
This signal is triggered before (before
is true) and after (before
is false) the call to MGTransfer::copy_to_mg which transfers the vector given to it to a multi-level vector.
Definition at line 68 of file multigrid.h.
boost::signals2::signal<void(const bool before)> mg::Signals::transfer_to_global |
This signal is triggered before (before
is true) and after (before
is false) the call to MGTransfer::copy_from_mg which transfers the multi-level vector given to it to a normal vector.
Definition at line 75 of file multigrid.h.
boost::signals2::signal<void(const bool before, const unsigned int level)> mg::Signals::coarse_solve |
This signal is triggered before (before
is true) and after (before
is false) the call to the coarse solver on level
.
The coarse solve will be done with defect[level]
and returned in solution[level]
, which can be inspected by the user using this signal.
Definition at line 87 of file multigrid.h.
This signal is triggered before (before
is true) and after (before
is false) the call to MGTransfer::restrict_and_add() which restricts a vector from level
to the next coarser one (level
- 1).
The vector defect[level-1]
will be updated between these two triggers and can be inspected by the user using this signal.
Definition at line 98 of file multigrid.h.
boost::signals2::signal<void(const bool before, const unsigned int level)> mg::Signals::prolongation |
This signal is triggered before (before
is true) and after (before
is false) the call to MGTransfer::prolongate() which prolongs a vector to level
from the next coarser one (level
- 1).
Definition at line 106 of file multigrid.h.
boost::signals2::signal<void(const bool before, const unsigned int level)> mg::Signals::pre_smoother_step |
This signal is triggered before (before
is true) and after (before
is false) the call to a pre-smoothing step via MGPreSmoother::apply() on level
.
The smoother result will be stored in solution[level]
and can be inspected by the user using this signal.
Definition at line 117 of file multigrid.h.
boost::signals2::signal<void(const bool before, const unsigned int level)> mg::Signals::post_smoother_step |
This signal is triggered before (before
is true) and after (before
is false) the call to a post-smoothing step via MGPostSmoother::apply() on level
.
Definition at line 125 of file multigrid.h.
boost::signals2::signal<void(const bool before, const unsigned int level)> mg::Signals::residual_step |
This signal is triggered before (before
is true) and after (before
is false) the computation of the residual vector on level
, including the result of edge_out and edge_down.
Definition at line 133 of file multigrid.h.
boost::signals2::signal<void(const bool before, const unsigned int level)> mg::Signals::edge_prolongation |
This signal is triggered before (before
is true) and after (before
is false) the execution of edge_in and edge_up.
