Abstract: It is essential to predict the ship resistance during the process of design and optimization of the ship hull form with respect to the resistance reduction. With the development of computational resources, Computational Fluid Dynamics (CFD) has been being widely used in calculating the ship resistance. However, level of accuracy of the numerical simulation significantly depends on human skills. This study is aimed to predict ship resistance, sinkage and trim in calm water by using unsteady RANS method. The effects of grids on simulation results is analyzed by performing some simulations on a sequence of systematically refined grid. The study comprises the numerical results of calm water calculation for the DTMB Model with available experimental results. The simulation is performed by using commercial solver Star-CCM+.
