K-E turbulent model is also utilized to capture details around the planing hull and, correspondingly, force acting on the hull. Furthermore, an individual mesh is adopted by combination of structured and unstructured mesh. To verify capability of the considered mesh, steady state solution of a planing hull is investigated and it is observed that numerical settings are adequate for determining planing motion. Finally, a hard chine planing hull is considered and dynamic sinkage and trim are computed. Comparisons of the obtained results with experimental data show a relatively good agreement and it can be concluded that the presented method can be used for practical studies in initial design.
