“…In the simulation geometry settings, the design geometry of the draft ship must be in the form of solid bodies. The design geometry and boundary conditions used as space boundaries in the simulation process are shown in In determining the multiphase model, there are three types of multiphase modeling in Ansys US software (Ansys, 2020), namely Eularian, VoF, and Mixture. VoF modeling of two phases with a special free surface by tracing the grid mesh that has been made.…”
