Standard Dynamics Model (SDM) is computed to validate the prediction of dynamics derivatives using grid generator “HexaGrid” and flow solver “FaSTAR”. The static and dynamic derivatives are computed at M=0.6, Re=2.31×10(exp 6), α=0-20deg. The forced oscillation method is employed to compute the dynamic derivatives. The effects of local time step and number of inner iteration are investigated. The computed results show good agreement with wind tunnel data. It is found that we have to evaluate the dynamic derivatives of SDM using unsteady simulation since the effects of Czα and Cmα are rather large, and these are not considered in the steady simulation.
