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. More information can be found here.

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".
