radiation modeling
 

Hi I am trying to model how sunbeams can increase the temperature in a room. In real life the beams hits say the floor or a wall. these walls are heated by the sun. The temperature in the room now increases due to warm walls due to convection and back radiation.

My question now is Is it possible in CFX to model the convective heat from the wall due sunbeams without modeling the wall as a solid and using conjugate heat transfer
