This paper reports on the applicability of the Lattice Boltzmann based free surface flow solver elbe to the simulation of complex ship-ice interactions in marine engineering. In order to model the dynamics of these colliding rigid multi-body systems, elbe is coupled to the ODE physics engine. First, basic validations of the ODE collision and friction models are presented, particularly focusing on interacting triangle meshes that later will serve to describe the ice floes. Then, the basic methodology and initial validation of the fluid-structure coupling of elbe and ODE is presented. Finally, performance is addressed: As elbe uses graphics processing units (GPUs) to accelerate the numerical calculations, the coupled numerical tool allows for investigations of ship-ice interactions in very competitive computational time and on off-the-shelf desktop hardware.
