You have to identify what it is that you want to heat up, and were that is in the box.  If you want the walls of the box to heat up, then you paint the walls black. If you want a piece of meat inside the box to heat up, like a solar cooker, then you want the walls of the box to be mirrors, but those walls should be angled to reflect the direct rays toward the meat.


I have used Ray Tracing software (not ANSYS) to do both diffuse reflections and specular reflections toward a sensor entrance.
