A Ropax hull resistance has been studied with OpenFOAM considering different Froude numbers, trim angles and drafts. The simulations have been set in calm water, model scale, using a multiphase domain implemented with a volume-of-fluid method and a SST k-ù turbulence model. The first simulation has been run even keel at design draft, Fr=0.2, both with the hull fixed in its original position and with the hull free to sink and trim. Comparison of results with another RaNS code has been also performed. Next, systematic data collection has been done with the hull fixed in various particular positions, at Fr=0.20. Similar simulations at higher Fr numbers have been run; in these cases a coarser mesh has been used in order to achieve a less request of computational power and a more stable behavior.
