FiPy with coupled solutions has not been released yet, as we have been trying to resolve a few edge cases that cause test failures in certain configurations. FiPy's development code, as you found, is always available *without support* via svn and can be viewed at http://matforge.org/fipy/browser. The code in trunk/ is always what we intend to eventually release. > On a similar note, I found a wonderful script for coupled system written by > Jonathan: > http://matforge.org/fipy/browser/trunk/examples/cahnHilliard/mesh2D-coupled.py Actually, I think Daniel wrote that, despite my name appearing first. > Since it is the only example I can find of this class of problems, I've been > trying to understand it to the fullest extent.

You would need to install all of FiPy's code from SVN trunk/ in order to run this example. > Thank you all for having been so incredibly helpful. Long live FiPy!
