PetscErrorCode PCMGMultiplicativeSetCycles(PC pc, PetscInt n)
Logically Collective
Input Parameters#
pc - the multigrid context
n - number of cycles (default is 1)
Options Database Key#
-pc_mg_multiplicative_cycles n - set the number of cycles
Note#
This is not associated with setting a v or w cycle, that is set with PCMGSetCycleType()
