Other » Problem about a 2D surface rotation

Hello,

I am working on the aerodynamics characteristics of a bullet surface after it is fired.After a bullet is fired it is rotated axysymmetrically and dashes forward in a flat projectile.I am implementing a 2D design for the phenomena.
But,the problem is how can I apply the surface rotation (the rotation of bullet in 2D) in FLuent? Please help me out..pe?

please help

Thanks !

I didn't find the right solution from the internet.
