Double Skin Facade - solar heating

[pim.krabshuis]

Greetings,

For my graduation project I'm designing a adaptive double skin facade. I'm trying to validate the system with Autodesk CFD but i'm having trouble getting the right bounderies for the double skin facade to get proper results. I have added a picture with the kind of function my facade must get. FYI I'm totaly new to Autodesk CFD.

In basic terms I want the air in the the air cavity of the double skin facade to heat up via solar heat/radiation and pull out the air of the adjacent rooms, a form of natural ventilation. I have tried several things but I'm at a total loss what bounderies i should use to calculate the heating of the air in the cavity.

For good mesure I have added my test file for you to get a better look at my situation. I hope somebody can help me with my problem so I can continue with the validation of my project.

Thank you in advance.

Sincerely,

Pim
