|Abstract:||Numerical simulations of fluids are indispensable in industrial product development cycles today. Often, these are turbulent flows, which are characterized by motions on many different scales. Resolving all these scales results in very high computational loads. On the one hand, the simulation of turbulent flows is of importance in industrial applications, but on the other, it is a classic example for simulations that usually are not tackled properly in todays industrial design processes. Limited by given development timeframes, the simulations need to obey other requirements than in academic research. A given turn-around time dictates the level of accuracy that can be achieved by the simulation on a given computing device. This usually results in simplified models, e.g. RANS, even in cases where highly instationary processes would demand different models. With modern supercomputers, it becomes possible to address these problems under the desired time constraints using highly scalable numerical methods and efficient load balancing strategies.
The trend shows that the distributiveness of computing systems keep growing and todays supercomputers are tomorrows industrial research computers. Knowing how these resources can be used efficiently to push the level of detail in simulation while keeping or reducing the turn-around times, is a key-argument for future investments.
