Harmonic Balance solver
 

Dear All,
I simulating sinusoidal flutter motion of airfoil. In starccm+, for Harmonic displacement, what value should be the input. As it asks as a vector in meters also real and imaginary values.
Simulating a simple NACA 0012 case with mean aoa = 2.89deg and amplitude of 2.41 deg. Freestream Mach =0.6, reduced frequency = 0.0808.
