Session

DescriptionComputational fluid dynamics is one of the main drivers of exascale computing, both due to its high relevance in today's world (from nano fluidics up to planetary flows), but also due to the inherent multiscale properties of turbulence. The numerical treatment is notoriously difficult due to the disparate scales in turbulence, the global Poisson solve for incompressible and weakly compressible flows, and the need for correctly resolving local features, as flow separation and shocks in compressible flows. The recent trend in numerical methods goes towards high-fidelity methods (for instance continuous and discontinuous Galerkin) which are suitable for modern computers; however, relevant issues such as scaling, accelerators and heterogeneous systems, high-order meshing and error control, are still far from solved when it comes to largest scale simulations, e.g. in automotive and aeronautical applications. In this minisymposium, we will gather experts from various institutions to discuss current and future issues of extreme scale CFD in engineering applications, with special focus on accurate CFD method. In particular, we will introduce the recently started European Centre of Excellence for Engineering Applications "Excellerat", with talks focusing on aeronautics, acoustics, automotive applications, and postprocessing suitable for large-scale simulation data.
