In order to help in achieving a correct design of structures subjected to wave impacts, CFD tools with a sufficient accuracy should be developed. But nowadays, modelling accurately both wave propagations and the resulting impact of a wave train on a complex geometry is still challenging. This paper deals with the introduction of a weak coupling between a Spectral method and Smoothed Particle Hydrodynamics (SPH), used as complementary techniques for modelling respectively wave propagation and high-dynamic impact of a wave train on a complex-shaped floating body. Comparisons with experiments are provided as a validation of these preliminary developments.
