After a fresh installation of FiPy on a Mac (OS X 10.10.2 and Python 2.7.6) I tried some example from the documentation, but they didn't work. So I tested FiPy using the built-in test routine (typing "fipy.test()" from the python shell) but after a long list of good doctests I got this log, with two failures: https://gist.github.com/alfrenardi/3b1ad5ff814077b18882
I tried on a fresh LTS Ubuntu installation too, but I got the same problem. There is any workaround? In my opinion this looks like a issue of the FiPy module, not of the platform.
It seems there are some problems with the tests. I made a request to the developers with a patch. I consider this question solved.
