In the simple model attached an incident irradiation of 10 W/m² is set at the internal walls, but when solving a value as high as ~50 W/m² is reached at this surface. Why?

Hi Natan,

I see in your model that incident radiation is defined in terms of W/(m^2 * sr). So there may be a factor of approx. 2*pi in between, since the surface approx. looks at a half space?

Cheers Edgar
