Abstract: Three mesh methods, solving the Navier-Stokes and the Euler equations, and a SPH method are applied to two fluid-structure interaction problems including rigid body motion.

The first test case concerns the simulation of the forced motion of a cone-shaped body close to the water surface. Here, the vertical fluid force and the surface motion close to the cone are compared with physical experiments.

The second test case is directly related to the simulation of a wave energy converter. A single floating body in extreme waves is modelled in one degree of freedom. Furthermore the interaction between the float and a counterweight, which is connected to it by a rope-pulley system, is taken into account. The vertical translations of the floating body are compared to measured results from physical tank tests.
