摘要：

In this contribution the coupling of the Smoothed Particle Hydrodynamics (SPH) method for fluid dynamics to Finite Elements (FE) for structures is discussed. The accuracy of the SPH method for hydrodynamics will be demonstrated by the case of a dam break in a container in which it will be made plausible that the experimentally observed free surface profile is influenced by a wet floor. The application of the coupled SPH-FE method to fluid-structure interaction is proven by the simulation of the drop of a flexible cylinder in water. A novel approach to generate free surface waves in an,arbitrary domain and validation for second-order Stokes' waves will be presented. Practical application of the methodology will be demonstrated by a study on waves inside flooded docks of an Amphibious Transport Ship and by the drop of a large canister into waves.
