jeniuswx is on a distinguished road
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.
