Hi everybody,
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 |

Hello Eli,
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? Thank you, Hava |
