having my Cl and Cd fluctuated
Hi everyone! I'd like to ask about the legality of my graph in Fluent if it is to be shown fluctuating (not convergence nor divergence). Can I take it as valid result? Or should I change anything in the parameter being used in Fluent? My case is about airfoil,NACA 9410,with its wind velocity 5 m/s. I'm going to use this type of airfoil as a blade in vertical wind turbine. Thank you.
