Dynamic stall on 2D aerofoil
 

Hi,

Im trying to model dynamic stall on a 2d aerofoil, by both plunging motions and pitching motions (separately at first, but eventually adding both motions together). How do I set up a user-defined subroutine to allow the aerofoil boundary to make these motions?

u can modify the NS equations by using a moving frame of reference ...
