Aldo,
Actually it is far easier than I thought. I have added the
argument -vecscatter_reproduce
that will cause the receives to always be processed in the same order
(though order or
operations in the MPI reductions may still result in slightly
different convergence histories.)

Aldo,
I would scale the turbulence equation to match the scaling of the
rest of the equations.
I suspect you are ramping up the CFL number too quickly. For a
"continuation" type
Newton method to work well (in my mindset anyways), you need to have
the solution
well converged b
Aldo,
1)Have you made runs where you require, say -ksp_rtol 1.e-12 to
eliminate the effects of
not solving the linear systems accurately?
2) Have you run the exact example that you ran with geometric
decomposition also with
the parmetis decomposition? Is that what you sent? (This is t
