Radiation mechanism in FLOW-3D
 
I want to know if FLOW-3D calculates the radiation mechanism of thermal transfer. I mean the heat transfer between 2 solids at a different temperature. We see that you only can define an emissivity to void but not an absortivity.
Also we have done an example with a thermal shadowing area and a body heated at high temperature and it seems that there is not distance-heat radition transference
Thanks in advance

you are right, the radiation model in flow-3d only accounts for fluxes from a surface to infinity. There is no model to model radiative heat exchange between two bodies.
