    VTT researchers have applied RANSE calculations to ship hydrodynamics since 1992 starting with water-jet inlet analysis. The CFX code was used. In later simulations the RANS solver FINFLO has been used. The FINFLO code has been tailored and developed to suit the needs of ship hydrodynamics. The two major applications are simulation of the flow field around ship hull including free surface and simulation of propeller flows. In ship hull simulations free surface and dynamic trim form the major challenges. To solve these iterative procedure and deforming grid has been used. In the area of propeller flow simulations sliding mesh technique for modeling interaction flow and simple cavitation model has been implemented recently.
