radiation intensity boundary condition

Farid Khalvati
Hi
For radiation modeling, I have solar radiation of 600 W/m2 emitted to a window.radiation in participating media is turned on and I added radiation intensity boundary condition for the window, but the unit of the boundary is W/m2.sr.it's clear I have to divide the solar radiation of 600 w/m2 by a solid angle.my question is: what's the solid angle for 2D modeling of a plate?Is it pi or 4pi?
I would appreciate If anyone can answer my question.
