Dear all,
I'm new to fluent and I'm trying to simulate a conjugated heat transfer case.
The model is made by a solid metallic plate, wich one of two surface is exposed to open air (on the other side I set a wall boundary at constant temperature). I modeled the open air domain too. The exposed surface is reached by a heat flux. A part of the thermal power flows through the plate (to the low temperature thermal sink), the remainder part goes to open air (irradiation and convection). I am interested to estimate the radiative flux from plate surface to air due to surface temperature.
I tried to simulate this surface setting an interface between the two domains, but the wall and wall shadow boundaries that come out don't allow me to set both a heat flux and a radiative behaviour contemporary.
How can I solve this problem?

Thank you
