The overset field-panel method presented in this paper solves the integral equation of the time-linearized transonic small disturbance equation by an overset field-panel scheme for rapid transonic aeroelastic applications of complex configurations. Using the high-fidelity computational fluid dynamics solution as the steady background flow, the present method shows that simple theories based on the small disturbance approach can yield accurate unsteady transonic flow predictions.
