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

      Hussein,

      Did you also alter the material properties to react to the non-gray radiation?

      material properties are the same except for distributing the solar intensity and absorption coeffcient into spectral bands when solving for non-gray .. could you please let me know what properties to alter ..
