wavelength dependent scattering coefficient
 

Hi all,
It is possible to define different absorption coefficients for each waveband in Fluent.
But for scattering coefficient, Fluent only gets a constant value or polynomial function.
It seems that there is even no way to write a UDF to define waveband dependent scattering coefficient.
Can anyone please help me how to define different scattering coefficients for each wave length for Fluent DO radiation modeling?

No answer?!
Please give me a clue if you possibly can.

Hello, have you solved this problem? I can not find the way to solve it though I have read your question profile at reseachgate. Thanks
