Modeling glass window in fluent
 
Hi, would you please tell me how I can modeling glass window in fluent?
I want to modeling a closed glass window in a room in summer.Do you know how I can set a transparent material in fluent?

What you want to simulation? radiation or thermal transfer? You could set the specific heat and thermal conductivity for the radiation or thermal transfer.

I want to considering solar radiation through glass window, conduction and convection heat transfer. actually calculating the effect of the glass window in hot summer days on my room. I wanna know, how I can define the transparent material in fluent, which act like glass window. if you know tell me by detail.
thanks.

solar radiation
 
In Model, you can choose radiation then S2S Model and activate de Solar Ray tracing.
Then in Material Panel, you have to create a new material for glass (please find properties of glass online).
In boundary Condition, in the Window-wall you have to choose in Thermal "Mixed" and fill the conditions you chose. In Radiation, for the BC Type you scrool down to semi-transparent.

I totally agree with you but still I confused which solar radiation type which is more compatible solid media

I also want to use openfoam to make an HVAC simulation in a bus with cooling ventilation and solar radiation through the windows. However, I don't have any clue. I am a student and a I am new with this program.
Could anyone help me? What tutorial/boundary conditions should I follow/use?
Thanks.
