                                                    It isn't obvious to me that Comsol Multiphysics is the best tool for your task.  Other people report using Monte-Carlo ray-tracing methods to do this kind of work.  If you haven't already read the literature about using those methods, you probably should.  Good luck.

This blog and the links at the end of it, as well as this model can get you started on modeling a solar concentration system with the Ray Optics Module.
Best,
Jeff
