Macro access radiation temperature DO and P1 models
 

Hi everyone,
in order to perform a series of calculations inside an UDF function I will need as imput the value of the radiation temperature cell by cell

At the moment I'm using a macro to compute this value based on the incident radiation:

P1 model:
T_radiation = pow((C_P1(c,t)/4./5.67e-08),0.25);

or

DO model:
T_radiation = pow((C_STORAGE_R_XV(c,t,SV_DO_IRRAD,0)/4./5.67e-08),0.25);

Since this variable is already computed by Fluent (at least from version 13) I was wondering if there is a macro that allows me to access it directly

Many thanks
