A chapter in High Performance Computing in Science and Engineering ‘13, 2013, pp 295-319 from Springer

Abstract: Abstract The most important aspect for simulations in industrial design processes is the time to solution. To obtain highly detailed results nevertheless, massive computational resources have to be deployed. Feasibility and applicability of HPC systems to this purpose is the main focus of this paper. Two different numerical approaches, implemented with parallelism in mind, are investigated with respect to quality as well as turn around times on large super computing systems. The one approach compares the efficiency of high order schemes on coarser meshes to lower order schemes on finer meshes. The second approach employs a zonal coupling of LES and RANS to limit the computational effort by using solution adapted models. Three industrial use-cases evaluate the performance and quality of these approaches. General optimizations are presented as well as solutions for load-balancing.
