why doesn’t non-gray discrete ordinates radiation method account for emission?

      hi

      when I modeled solar thermal convention using the discrete ordinates radiation method with wavelenght-independent absorption coefficient (gray model), it accounted for emission but when I change to wavelength-dependent absorption coefficient, i.e., spectral bands (non-gray), it gives zero volumetric emission. .. is this by default or maybe I've done somethings wrong .. thank you ..

      regarding
