Dear all CFD experts;

I am going to calculate aerodynamic dynamic coefficients and derivatives over a body-wing geometry. I know that I must oscillate my geometry in some angular displacements, but :

1- Which of pitch,plunge,roll or yaw motions must be considered and studied? I mean in dynamic coefficients and derivatives, which of them are necessary to investigate?

2-What is the rule to choose magnitude and frequency of,for example, sinusoidal excitation?

3-Any reference about this subject?

4-After calculating Lift,Drag and Moment coefficients versus time (or AoA and Side slip angle), what are the methods to calculate aerodynamic derivatives?

Any guide is appreciated.
