Toward Quantifying Uncertainties in Large-Scale Simulations of Engineering Flows – 2019/08/29

Toward Quantifying Uncertainties in Large-Scale Simulations of Engineering Flows Understanding the complex physics of wall-bounded turbulent flows is of utmost importance, considering the presence of this type of flows in various engineering applications. To this end, the use of high-fidelity approaches such as DNS (Direct Numerical Simulation) and LES (Large Eddy Simulation) has proven to be advantageous. There are, however, at least two main challenges that these approaches have to deal with. Fig. 1. Error isolines of mean velocity profile (top) and turbulent kinetic energy profile (bottom) of turbulent channel flow at friction-based Reynold number 300 simulated by Nek5000 The

Enabling the future of CFD for external aerodynamics optimization with exascale systems – 2019/07/31

Enabling the future of CFD for external aerodynamics optimization with exascale systems On June 11th, 2019 In Norway, a hydrogen refuelling station exploded. The whole hydrogen refueling station network had to be shut down. Toyota and Hyundai are both halting fuel cell sales in Norway. Elektrek – Hydrogen Station expoldesAs transportation companies struggle to find the way out of fossil fuels,  this event illustrates how safety aspects can become a brutal showstopper. In particular, accelerating too much the release to market can jeopardise the efforts of a whole community. Since the public is now aware of the climate urgency, and the competition is open

EXCELLERAT to Bring HPC Applications to Engineering Industry – 11.05.2020

EXCELLERAT to Bring HPC Applications to Engineering Industry High-performance computing (HPC) specialists are looking forward to the technological improvements that should arrive in the coming years as supercomputers approach the exascale. New approaches in hardware design (including new processors and high-bandwidth memory) and in application development (for example, code parallelization and data processing) will expand the power of supercomputing and therefore make it possible to solve new kinds of complex problems. Kick-off meeting EXCELLERAT at HLRS in Stuttgart – ©HLRS Industrial research and development in engineering is one application area of high-performance computing that is likely to benefit from these
