Direct irradiation through Single Glass
 

I am using Discrete Ordinate(Non-Gray Model) of Ansys Fluent.Pls does anyone know how to set the sun direction to go into a 3d model(Single Glass) in Ansys Fluent not CFX.I have looked thru the manual of Ansys but things seems to be going wrong somewhere i dont know.

I am attaching the illustration of my idea.Pls help.

I have the same problem. Have you solved that?
I tried the semi-transparent in the glass boundary, radiation drop-down list, and add the irradiation. But the result doesn't seem good.
Anyone can help?
Thanks a lot!
