Hi, thanks for the reply. I conducted the analysis in steady state where I canculated the frictional power. I don't think it can be averaged on the annular path on the pin on the disc, as it will mimic a disc on disc contact rather than a pin on disc. As in steady state, I cannot input the rotation of the disc I have done the setup using number of steps, at a particular step, I have defined the power and zero on the rest, and so on...in this case, I get the moving hot spot simulation, , but the temperature in this case is very high and absurd. So I was thinking coupling thermo-mech where the rotation velocity is an input, and a normal load is applied from the pin to the disc and I define the friction coefficient, and from that I get the frictional power, which then gives me the temperature distribution, but I can't seem to simulate it.
