Dear community,

Im new here and looking forward to get help and learn more about Ansys CFD.

Im working with Fluent to model a double skin facade. I created a 2D Model which consinst of two wall boundaries for the two layers of facade glass and an atmosphere in front of the first layer of glass.
The radiation is implemented on a semi-transparent wall on the outer edge of the atmosphere.
Unfortunately the radiation will not be transported through the semi-transparent wall representing the glass pane of the facade.
Does anybody know why that is? I gave the wall a thickness and defined the material glass. The wall is coupled.
The description of the model and the result are in the pictures:

I would really appreciate some thoughts on this topic.
Thanks a lot already.

Hello CB,


I'm else working with semi-transparent medium. You can trate this medium like a frozen fluid.


Set frozenFlow in fvSolution and its done, you can solve the RTE with P1 or fvDOM.
