After installing petsc4py, you can do make docs in the top level
source tree, and the docs/ directory will be populated. For this to
work, you need sphinx and epydoc installed.

Quick question (out of ignorance): does it matter that the HEX8 may still be
arranged in an unstructured fashion? Meaning, that although I use brick
elements, my grid does not have a structured grid appearance.

This is fine. PCGAMG does algebraic multigrid so the mesh doesn't matter in
its use.

Ok, so I ran my fluids problem with -pc_type jacobi. This time it did not
return with “inf”, but there was no convergence.
Here is the first 10 iterations:

Good. This seems to confirm that ILU(0) was the problem.
It is not a surprise that Jacobi is

This works quite well and does not cost some much, especially since I
The difference between IS(1), IS(2) and IS(1)',IS(2)' is that they
operate on two different matrices. The former operate on A whereas the
operates on S and these matrices have different sizes so it's not
obvious to me that they IS would be identical? I guess it depends on the
initial ordering

The default preconditioner with ILU(0) on each process is not appropriate for
your problem and is producing overflow. Try -sub_pc_type lu and see if that
produces a different result.
Is this a Stokes-like problem?

This is Euler flow equations discretized with SUPG. The mesh is made of
