Hi, I noticed that the FieldSplit functionality is now in the latest release, but I've been having trouble finding examples of how to use it. I'm using fairly standard stabilized equal order P1 and P2 tetrahedral elements for variable viscosity/density incompressible flow with the DOF end to end (p0p1p2...u0u1u2...not interleaved) so I think I need to use the general PCFieldSplitSetIS. Would anybody be willing to point me to some example code that uses the current field split functionality? Is it basically finished in the latest release or is there still reason to use petsc-dev if that's what I'm working on?
Thanks, Chris
