Applications of Navier-Stokes with free-surface solvers for applications in naval hydrodynamics started about ten years ago. Those solves show great interest by allowing a notable improvement in computations accuracy, mainly due to non linear free surface conditions and viscous effects. Nowadays, they are mainly used for resistance applications by almost all research institutes or industrial parties. Recent development of those solvers allow their application in other fields of hydrodynamic, such as seakeeping and maneuvering. Thus, the field of application of these tools is incredibly wide, in particular for unsteady simulations, allowing to model the whole behavior of a maneuvering ship.
The development of ICARE solver is going in this way, we present in this paper the applications on steady and unsteady maneuvering simulation of ships. To achieve this goal, six degrees of freedom, and rotating appendages capabilities have been developed and are presented.
