A method is presented to calculate the resistance of a high-speed displacement ship taking the effect
of sinkage and trim and viscosity of fluid into account. A free surface flow field is evaluated by solving Reynolds
averaged Navier-Stokes (RANS) equations with volume of fluid (VoF) method. The sinkage and trim are computed
by equating the vertical force and pitching moment to the hydrostatic restoring force and moment. The software
Fluent, Maxsurf and MATLAB are used to implement this method. With dynamic mesh being used, the position
of a ship is updated by the motion of “ship plus boundary layer” grid zone. The hull factors are introduced for
fast calculating the running attitude of a ship. The method has been applied to the ship model INSEAN2340 for
different Froude numbers and is found to be efficient for evaluating the flow field, resistance, sinkage and trim.
