This model solves a 2D potential flow around a cylinder or a naca airfoil, placed in a uniform flow. The lift force is evaluated by both the integration of pressure and the Kutta-Jukowski approximation. In the Airfoil case, a non linear iteration is done by means of a pseudo-newton scheme, to ensure that the Kutta condition is verified.
