Ah, that's why PCFieldSplitGetSubKSP() is in petscksp.h, along with MatSchurComplement stuff.

Yuck. So using two different bad ways of resolving the same problem! Not good. I'm inclined to get rid of petscpcmg.h anyways (and its 3 Fortran versions). Then we are at least solving the same problem with only one bad way. Barry
