Hi, I would like to know how to change the number of multigrid levels in AMG. I have tried PCMGSetLevels, which does not work, and I suspect that the PC is not recognized as a multigrid preconditioner, because I'm PCGAMG as the preconditioner to the coarse level solver of a PCMG. However, I do not understand why it is not recognized as a multigrid preconditioner.
Please let me know if the above is unclear, Erik
