Numerical study of the strongly nonlinear extreme wave interaction with a floating structure based on the open source package OpenFOAM is presented. The numerical solver is based on the Navier-Stokes equations, and the Volume of Fluid (VOF) method is employed to capture the complicated free surface. A two-dimensional numerical wave tank is established, which can generate various types of waves by given the free surface position and the water particles velocity at a fixed boundary according to wave theories. By means of the 6 degree-of-freedom (6DoF) motion solver and the deformed mesh technique, the simulation of body motion is achieved. The linear waves and focused wave are generated and compared with theoretical results to validate the numerical wave tank firstly, and then the strongly nonlinear wave-structure interaction is simulated. The motion responses of the floating structure under extreme wave are predicted. Both the motion responses of structure and the complicated free surface are compared with corresponding experimental measurements and show satisfactory agreements. The flow field and the green water phenomena are analyzed based on the numerical results. It implied that the present numerical model is efficient and accurate for dealing with the strongly nonlinear wave-structures interaction problem with both the violent free-surface flow and large amplitude body motion.
