A simulation environment for the numerical simulation of liquid-solid body dynamics

For CAE (computer aided engineering) of satellites with large amounts of onboard liquid, analysis tools are required that simulate the behaviour of the combination of the satellite and the liquid. In the present report a technical concept is presented for a simulation environment for the numerical simulation of liquid-solid body dynamics. The simulation environment supports the structured approach of partitioning in which models for liquid motion and solid body motion are independent. The feasibility of the numerical method is demonstrated in a separate paper.
