  I apologize for the interruption; however, I have been looking at FiPy for possible use in solving steady state compressible axisymmetric flow problems (nozzles).

We haven't specifically programmed axisymmetric coordinate systems, everything at this stage is cartesian.
It is possible to use a small-angled wedge shaped mesh to simulate axisymmetric problems (will have some
associated error) within a cartesian system. I haven't done this using FiPy, but it should be possible.

As far as flow is concerned, we have a cavity Stokes flow example. This can be found in 'examples/flow/stokesCavity.py'
from the base FiPy directory. You will have to checkout a new copy of FiPy.


  I have read the FAQ and the users manual; however, I’m still not sure if I can set up such a problem in FiPy.

We have no axisymmetric examples as yet. We also had no flow examples in version 1.0. The manual on the web page is
for version 1.0.

  If you could nudge me in the right direction for 1) Is FiPy appropriate? and 2) Is there such an example? I would be very grateful.

You'll have to make your own decision based on what is available.
