udf code for anisotropy turbulence model- square duct
I'm trying to simulate a fully developed flow in square duct to predicate the secondary flow motion.
I already obtained this kind of motion using RNG model but i have to compare with the anisotropy turbulence model or so called (nonlinear model)
since its not available in fluent so i need to use UDF , so do you guys have the udf code so i use it ???
thank you much for help
Could you please tell me how you achieved secondary flows with RNG, because I tried RNG with enhanced wall treatment with all its options in fluent, with no success. Did you use udf or the simulation was transient?
