The resistance of a cargo ship is calculated by numerical towing tank. RANSE multi-phase parallel solver with K-w SST turbulent model and VOF formulation is applied. Computational results from double model (without free surface) are used to obtain 1+k in Hughes’ method and those with free surface are analyzed by both Froude and Hughes’ approaches to investigate model and full scale correlation. ITTC recommended uncertainty study is carried out to evaluate numerical error due to grid density. The computed wave elevation, wake distribution and resistance components by fine, medium and coarse meshes are cross-compared and validated against experiment data where applicable. It is found that grid resolution has most effect on wave pattern. The predicted friction and viscous-pressure resistance coefficients are relatively grid independent from present numerical simulation
