Energy source term in Discrete Ordinate Method
 

Hello Everybody,

I have a configuration where I need to estimate the radiative properties. To achieve this, I use the discrete ordinate method in Fluent Software.
Nevertheless, I want to estimate by an UDF, the radiative source term in the energy equation, that is to say the divergence of the radiative flux.

I am familiar with UDF, but in documentation, very poor information are given (for example on the variables used in DOM). Consequently With discrete ordinate method, I have no Idea how to do this....
If somebody has any experience and want to help me...

Thank you very much
