Hi all, i'm working with DO radiation in Fluent.
I want to know how to set the value of "absorption coefficient(1/m)","diffuse fraction","internal emissivity","absorptivity","transmissivity". And where can I find these properties of glass.
Thank you in advanced.

hello,Dorasemon,firt what are simulating(2d,3d)? when u use radiation the absorption coefficient appears in the material panel (properties), and u can see absorptivity,transmissivity in the boundary condition ( radiation.? use BC type for specific material
