hello
i m doin transonic aeroelastic analysis over an airfoil so i need to find the flutter speed, so can anyone tel me the procedure to find the flutter speed plzz,
thank u

In some cases you can use quasistatic aeroelastic theory to find the flutter speed. If it's good enough for you it, than you only need to calculate the lift coefficient depending on angle of attack.

If you want 2 way FSI, you can do a transient simulation. If you're above the critical velocity the flutter should develop by itself (just like a vortex street behind a cylinder). It's a very expensive calculation though.
