Hi

I have a problem with modelling radiation through glass in fluent. In case of glasshouses, Hvac applications the sun light comes through the glass, and the infrared rad. is reflected back to the room increasing the temperature inside. To model such a case, i want to use DO radiation model in fluent, but until now i cant set different transmission coefficient for the different radiation bands. Fluent let me to set only 1-1 value for the internal and external emission coefficient. Is there anyone who can help me how to model such a case? I think this is a very current topic because of energy-saving of buildings. I hope there's someone who has experience with this.
