Fair enough. I'm still not certain what the original question was though. Were you asking whether one can model some nucleation process or other using a CH equation in fipy? All I would say is that if you think can write down the equation, initial conditions and boundary conditions to whatever it is you are interested in then, yes, you can probably get a reasonable answer using fipy in one way or another.
