## Abstract Numerical solution of flows that are partially bounded by a freely moving boundary is of great importance in practical applications such as ship hydrodynamics. Freeβboundary problems can be reformulated into optimal shape design problems, which can in principle be solved efficiently by
usually calculated with a black-box method. Such a method consists in using finite differences to determine the gradient We explore the praticability of optimal shape design for flows modeled by the Euler equations. We define a functional whose of the functional, and therefore, for each gradient co
