Hi, I have a couple more questions: 1) The problem is a quarter symmetry and I am solving the problem in the first Quartile how can I specify the symmetry of the experiment? As if I take the *dT* on *(0,r)* it is different than *(r/math.sqrt(2), r/math.sqrt(2)) *although it should be as both points are on the radius. 2) Finally, is this the right way to get the *dT* (cell-variable) value inside each step? *dT(((0,), (r,)))*
