template<typename OptionsGroup >
Initial value:=
"Set to 'False' to disable pre-smoothing altogether (\"cascading "
"multigrid\"). Note that pre-smoothing can be necessary to remove "
"high-frequency modes in the data that get restricted to coarser grids, "
"since such high-frequency modes can introduce aliasing. However, when "
"running only a single V-cycle as preconditioner, the initial field is "
"typically zero, so pre-smoothing may not be worthwile."
