Hi Ajay!
Glad to hear that you are diving into FiPy.
You will see that FiPy includes an explicit diffusion term to
illustrate that one can
violate the stability criterion. Of course, this is why most of the
time you would
pick the implicit diffusion term. There are a couple of paragraphs in
Numerical Recipes
that discuss stability and amplification factors. (I apologize if you
already know these
things.) If this is the first time you are hearing about this, then
read on.
Regarding stability issues, a good thing to do is to have both the
FiPy users manual
and a copy of a book like Numerical Recipes in front of you at the
same time. That
should provide some additional background information needed to really
understand
the FiPy users manual.
Does this help? Have I missed the point of your question? Maybe you
could ask the
question a bit differently?
Good luck!
Best,
Dan

Another Question........
Is there any stability related issue in solving phase field problem
with respect to mesh size and time steps.
Thanking you all in advance
I'm really liking Fipy.
Really thankful to Dr. Daniel wheeler , Jonathan Guyer and his team.

Is there any methods to solve stiff differential equation in fipy.
seacuse in my model in need to couple my PDE with stiff differential
eqn.
or i had to goto scipy to solve stiff eqn.
