Hello all! We have a simple problem, but don't know how to set it up in FiPy: We are interested in transient heat transfer in a 1D spherical system in radial direction. How do we set up the diffusion term (or the mesh) for such a problem? The equation would look like: dT/dt= 1/(C *r**2) d(k*r**2 (dT/dr))dr + qdot/C
Thanks! Regards, Burak
