The SimLab "Highly Scalable Fluids & Solids Engineering" aims at supporting users of the engineering sciences who have already developed parallel codes but need support for the use of massively parallel systems regarding high scalability, memory optimization, programming of hierarchic computer architectures, and performance optimization on computer nodes.
Examples are finite-volume, finite-element, and finite-difference methods which are based on block-structured body-fitted meshes and/or unstructured Cartesian grids. These methods developed by various groups at RWTH are used to investigate problems in aerodynamics, aeroacoustics, aeroelasticity, and combustion.
The SimLab has recently started a cooperation with the Complex Phenomena Unified Simulation Research Team at AICS, Riken, Japan, in the frame of the Joint Laboratory for Extreme Scale Computing (JLESC).
The project “Comparison of Meshing and CFD Methods for Accurate Flow Simulations on HPC Systems” aims at finding efficient numerical methods for running large-scale computations on future HPC hardware by juxtaposing state-of-the art simulation technologies on the JUQUEEN at the Jülich Supercomputing Centre and the K-Computer at the AICS in Kobe.

The SimLab and the Jülich Supercomputing Centre organized a workshop together with the German Aerospace Center (DLR) on May 25, 2016. The event aimed at identifying common research interests between the the C2A2S2E group of the DLR, mathematicians, fluid mechanics engineers, visualization-, and HPC-experts of JSC and JARA-HPC. The workshop took place within the frame of a Memorandum of Understanding (MoU) between the DLR and Forschungszentrum Jülich. This MoU focuses on HPC methods that are mandatory in simulating all potential in-flight conditions of airplanes and was agreed on within the DLR projects “Digital-X” and its successor “VicToria”. Based on the given talks, research overlaps could be identified in in-situ methods for visualization and online simulation processing, and Cartesian mesh methods for finite volume, discontinuous Galerkin, and Lattice-Boltzmann methods. Furthermore, parallel-in-time integration methods for fluid mechanics and potential funding opportunities within Horizon 2020 were discussed. As such, this workshop enabled all participants to get to know each other and served as a basis for future cooperations and knowledge exchange between experts in their fields.
5th Korean-German Workshop
Dr. Andreas Lintermann, head of the SimLab FSE has recently participated in the 5th Korean-German Workshop on CFD and aeroacoustics methods and applications applied at the Korea University, Soul, the Institute of Aerodynamics, RWTH Aachen University, and JARA-HPC. The workshop was held on Jeju Island in South Korea and Dr. Lintermann gave a talk on "Parallel Mesh Generation" and "Simulation of Respiratory Flows".
