I want to solve 2D - temperature equation in matlab by FE method in cylindrical system(r z phi) and symmetric about angle PHI. The derivative of temperature to time is zero,but our elements generates temperature,that means is Laplacian of temperature is not zero and instead of that Laplacian of temperature is a function,such as a function of (x,z,T).

can anyone help me to write this program in MATlab?
