Research Focus

The chair for Applied Supercomputing in Engineering deals with the simulation of large technical systems, especially in the field of fluid mechanics as well as multi-physics / multi-scale systems in combination with fluid mechanics. The focus is on complex simulations and their efficient implementation in computer programs. This requires the entire chain from numerics development (math), efficient implementation (comp. science) to production (engineering).

The fields of application are thereby mainly driven by real-world applications and research, defined by industrial or medical project partners. The simulation of such real-life systems typically requires the use of high performance computers. Therefore, in addition to the modeling and analysis of physical phenomena, one focus of the laboratory also is on efficient implementation methods of algorithms on supercomputers.The interdisciplinary research approach of the group is manifested in collaboration projects with partners from mathematics, engineering and computer science as well as several European supercomputing centers.

These kinds of simulations are very CPU-time intensive, even on the most modern supercomputers. Therefore, the schemes have to be highly optimized, in the numerical algorithms as well as in coding and implementation. The group develops the APES project (Adoptable Poly-Engineering Simulator), a tool box for simulations of CFD+X. It includes numerical methods for compressible and incompressible flows, Maxwell equations, and acoustics, scaling efficiently on up to 100,000 processes. The simulation methods cover all fields of methods with broad application fields as well as highly adopted algorithms for special purpose. The basis are mesh-based methods such as Finite Volume methods (FV), Discontinous Galerkin (DG) and Lattice Boltzmann (LB).
