Sažetak
This paper presents numerical simulation of wave loads on static offshore structures. The Naval Hydro Pack in OpenFOAM is used. Two phase free surface flow model is used with Volume of Fluid and Level Set method for interface capturing. Governing equations are discretized using the Finite Volume Method. Wave modelling with relaxation zones is described. Simulation of 3D dam break with fixed square column is carried out. Results are compared with corresponding experimental data. Next, a method for freak wave initialization using wave focusing is given. Wave components are obtained using standard wave energy spectra. Simulation of freak wave is shown.
