摘      要：In this paper a framework for efficient irregular wave simulations using Higher Order Spectral method coupled with fully nonlinear viscous,two-phase Computational Fluid Dynamics(CFD)model is *** model is based on solution decomposition via Spectral Wave Explicit Navier-Stokes Equation method,allowing efficient coupling with arbitrary potential flow *** Order Spectrum is a pseudo-spectral,potential flow method for solving nonlinear free surface boundary conditions up to an arbitrary order of *** is capable of efficient long time nonlinear propagation of arbitrary input wave spectra,which can be used to obtain realistic extreme *** facilitate the coupling strategy,Higher Order Spectrum method is implemented in foam-extend alongside the CFD *** of the Higher Order Spectrum method is performed on three test cases including monochromatic and irregular wave ***,the coupling between Higher Order Spectrum and CFD is validated on three hour irregular wave ***,a simulation of a 3D extreme wave encountering a full scale container ship is shown.
