1) This is a Cartesian mesh, so it will not work with unstructured stuff
2) This boundary condition only works for cell centered, but I think
you have that

The reason I suggested petsc-dev is that you would get all the
updates. With new components, this
is usually much much easier. You can install it yourself on the
supercomputer, using the MPI and
BLAS/LAPACK they have there very easily. Moreover, I do not know of a
single place that would not
install dev for you.
What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
