Question Ray Heating?

Hello. I want to simulate a concentrated parabolic photovoltaic and I need to calculate the heat flux and the temperature at the bottom-receiver(I use a silicon cylinder) of the compound parabolic mirror. So far the ray trajectories and the heat flux are calculated using the Geometrical Optics and the illuminated surface. The problem is when I use the Heat Transfer solid to solid and the Ray Source to see the temperature distribution. It gives me negative results for Ray power and Temperature of the receiver. So, judging from solar_dish_receiver and from thermally_induced_focal_shift I guess I am using wrong the Bidirectionally Coupled Ray tracing Study or I need to use the Solar Radiation option(trouble inserting initial coordinates) instead of Illuminated Surface?

Hi, did you manage to solve this? I am also struggling with a similar application. In my case I am modeling a photovoltaic module and some times I get negative values for the ray power, which curiously leads to very high temperatures across the module...
