This video demonstrates setting up and solving a thermo-fluids case using the Monte Carlo radiation model, a statistical radiation model in which a sample of photon’s histories are tracked through the system. With enough photon histories, a good estimate of the desired physical quantities can be obtained. This is especially suited, over other available methods, for modelling collimated beam style irradiation which is demonstrated in this video with an automotive headlamp case. Solar heat flux is given as an input and radiation is modelled through the air volume, front cover, and lens. The goal of the simulation is to predict the location of any thermal hot spots which occur from solar rays being focused through the lens of the headlamp assembly.
