Hi, everyone.

In FLUENT, the absorption coeff. of fluid can be calculated in user-defined-gray-band. so in this way the variation of absorbtion coeff. with wavelength are considered.

But the scattering coeff. and absorption coeff. of particle can't be done like that. right? Then what can be done for non-gray particle? And the UDF of DEFINE_DOM_SOURCE can solve this matter?

thanks a lot.
