chtMultiRegion(Simple)Foam + radiation
 

Dear All,

I am trying to use a radiation model in OpenFOAM. I am simulating a room with an hot block of aluminium inside.
What I need to simulate is radiation through the window of the room (that is modeled as a surface).

Do you have any idea about I can do this simulation?

I read the chtMultiRegionSimpleFoam (with radiation, i.e. multiRegionHeaterRadiation), but there is no an external surface through which radiation enters the domain (if I understood well).

Could you kindly help?
