hello,guys! i am modeling the light radiation with DO model, but there is a problem that confused me. the collimated beam (Perpendicular to the glass wall) radiated from the glass wall to an annular reactor with water, after the simulation, it get a shocking result that the light transmitted aslant (please see the contour of incident radiation and pay attention to the right, all boundaries in the reactor are walls)! The light dirrection is set to be vertical and the direction should be unchanged in theory, i don't know why this happen (the light source is regard as purely specular)! please help me! any help is appreciated, thanks!

the boundaries in the top, left and right are same in this case and to be opaque with the internal emissivity equals 1.

This problem seems to be specific to Fluent, so you'd better post in the Fluent forum.
