v57 v58 183 183 {{{#!td 184 184 Type of cycle to be used with the multi-grid method.\\\\ 185 This parameter determines which type of cycle is applied in the multi-grid method used for solving the Poisson equation for perturbation pressure (see [[ psolver]]). It defines in which way it is switched between the fine and coarse grids. So-called v- and w-cycles are realized (i.e. '''cycle_mg''' may be assigned the values 'v' or 'w'). The computational cost of w-cycles is much higher than that of v-cycles, however, w-cycles give a much better convergence.185 This parameter determines which type of cycle is applied in the multi-grid method used for solving the Poisson equation for perturbation pressure (see [[../inipar#psolver|psolver]]).
