Not only non-linear, but transient (ie changing) analysis. There's a direct correlation between Spice electronic elements and thermal elements: Electrical Thermal Voltage Temperature Charge Heat Current Heat Flow Resistance Thermal Resistance Capacitance Specific Heat * volume I used it to see if the placement of thermocouples in Rossi's "Heat exchanger" test would invalidate his results. http://lenr.qumbu.com/rossi_ecat_oct11_spice.php (I think that was the last version ... I didn't link it to my main page) A mesh of resistors models the structure in 2D (you can do it in 3D but that wasn't necessary) The resistors models the conductivity through the mesh A capacitor at each junction of 4 resistors models the specific heat You can then see how a temperature impulse propagates through the mesh. I got a qualitative answer, but I couldn't callibrate it to get a quantitative result. I expect much the same for the hot-cat.
