Multiple urf settings on different cell zones
 

Dear all,

haven't had the chance to use UDFs in FLUENT yet so i'm a complete newbie on this matter. I just would like to know if it would be possible to apply different under relaxation factors settings on corresponding different volume cell zones. As an example, considering a domain composed by two mesh cell zones, I would like to use two different urf settings to help the solution settle down and/or converging.

What do you think?
Thank you in advance

Please, any suggestions? Or just throw in what you think about?

Thanks
