Hi Everybody

I am facing a problem concerning the extraction of cell value from the radiation equation(s) [DO model]. Specifically, i am writing a UDF in which i have to read a value related to radiation equation from the computational domain in order to compute a source term of an another equation, but i cann't find the proper macro to extract it, reading the udf manual.
All we know that we can call the C_T(c,t) to read the temperature value from a cell. The question is what's the proper macro for the DO radiation model and if there is, and what's the proper syntax of it if i want to read the values of a 3 band non gray radiation model of a cell?

I would appreciate any helpful anwser
Thanks in advance

I don t know personnaly I work with the DO model, with non conform interface and I inject the profil of radiation on semi transparent from a optical software
My goal is a model more accurate

did you try using C_DO_I(c,t,ns) for cell intensity where ns = sg_disco * nb + i; i-> direction of intensity; nb= band-number;

you can use the following macro to access Radiation intensity of each cell:

where i is the number of grey band
