how to define a UDF for the incident radiation in DO radiation model
 
in the DO model for the radiation heat transfer modeling, under the radiation tab of the wall boundary condition definition, the semi-transparent media was selected, i want to use a UDF as a radiation source to add the incident radiation into the domain. the question: is it can be done in the fluent? and how and where to add this UDF into fluent? thank you !

I did the exact same thing a few days ago.
You can find te answer to your thread here:

In this example the BoCo is a heat flux, but you can use the same UDF for the radiation.
