GPU-accelerated large-eddy simulation of ship-ice interactions
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
