UDF:Define Heat Flux
 

Hello, Did somebody try to use DEFINE_HEAT_FLUX macros to add a radiation heat flux on a wall?

I have tryed, but it seems that nothing happens. Thus I have tryed to rebuild the existing Rosseland method using a modified thermal conductivity kh+(16*ng^2*sigma*T^3)/(3*kappa) and a wall radiative heat flux qw,r=-ng^2*sigma(Twall^4-Tcell^4)/psi, but I was again not successfully.

Do you have any ideas?

Thanks
