Optimized heating profile for the CP, when CP and TM are 20cm distant

I finally managed to run the heating profile optimization in Ansys. So I could take into account the radiative coupling between CP and TM. I used a CP that is 3.5cm thick and 20cm distant from the TM. It is possible to explore also other geometries (next steps).
First figure shows the convergence of the heating pattern. The numbers in the legend represent the iteration step (maximum is 40).



The second plot shows the evolution of the OPL increase, again as a function of the iteration step.



Last plot, shows how the coupling losses decrease as the heating pattern improves. It is clear that the loop, after 40 iterations, has not yet converged to the steady state. However, the best result of 50ppm residual coupling losses is astonishing!!!
