boudnary condition
 

Hi everyone,
i am starting with fluent and now i know how to mesh and set parametrs for simulation. But i can't find out how to change boudnary condition (velocity vector) during iterration. I want to get a polar of profile NACA4415, is there any way how to do it not manualy? I find some macros and UDF, but i am not sure how to use it. Thank you for any reply.
