EU-Project helps Engineering SME Improve Competitive Position – 2018/05/03

EU-Project helps Engineering SME Improve Competitive Position Current practice in the design of hydro-power plants is to determine empirically the most suitable design in a series of time-consuming experiments. However, SMEs in this sector have to face private and public tenders to sell their turbines in both national and global markets, where the competition is very strong and the development time is very short. The challenge facing Zeco was therefore to improve their design processes to remain competitive.  Their idea was to make extensive use of HPC-based high-fidelity simulations of flow in the turbines by using CFD-based tools. The development

First virtual EXCELLERAT All Hands Meeting (May 2020) – 2020/05/11

First virtual EXCELLERAT All Hands Meeting (May 2020) Due to the travel restrictions linked to the corona virus, we have successfully organised our first EXCELLERAT virtual All Hands Meeting with more than 40 participants. Instead of hosting it in Stockholm from 5th until 7th May, this was our team’s largest online conference so far. During this All Hands Meeting, the current status of all work packages were presented and our codes’ use cases were discussed. Moreover, we exchanged knowledge and experience on behalf of our working groups, and prepared our upcoming project review. To sum it up: We are even

New analysis methods facilitate the evaluation of complex engineering data – 2019/02/12

New analysis methods facilitate the evaluation of complex engineering data A further increase in the performance of supercomputers is expected over the next few years. So-called exascale computers will be able to deliver more precise simulations. This leads to considerably more data. Fraunhofer SCAI develops efficient data analysis methods for this purpose, which provide the engineer with detailed insights into the complex technical contexts. Simulations on supercomputers answer important industrial questions, such as how air flows behave in air conditioning systems, on rotor blades or for entire airplanes. In the coming years, new approaches to hardware design will make computers

Preparing Cloud Physics for Exascale – 2019/06/04

Preparing Cloud Physics for Exascale Cloud model (MONC) is an atmospheric model used throughout the weather and climate community to study clouds and turbulent flows. This is often coupled with the CASIM microphysics model, which provides the capability to investigate interactions at the millimetre scale and study the formation and development of moisture. One of the main targets of these models is the problem of fog, which is very hard to model due to the high resolution required – for context the main UK weather forecast resolves to 1km, whereas the fog problem requires 1metre or less. A major driver here

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 The design of the car of the future requires going over the usual RANS approach, since it fails to predict with an acceptable prediction accuracy features like transitional flows, instabilities, noise gneration, combustion efficiency. This in turn requires exascale systems, to sustain more high-fidelity simulations techniques, like LES or DES. EXCELLERAT paves the way to this transition.Five years ago, a report1 sponsored by NASA documented the results of a study to address the long range, strategic planning required in the area of computational fluid dynamics (CFD), including future

EXCELLERAT Team Meeting in Bologna (Nov 2019) – 2019/12/13

EXCELLERAT Team Meeting in Bologna (Nov 2019) In November 2019 CINECA hosted the successful EXCELLERAT Team meeting in Bologna. The purpose was to show the current success stories of all partners and to discuss how to push the use cases in the direction of exascale. First demos looked really impressive. It has been productive and a real pleasure. hosted the third annual Industrial HPC User Roundtable (iHURT) on December 3, 2019. The event offered a forum for HLRS and its industrial users to exchange perspectives on the state of the art in high-performance computing, specific computing challenges industrial users face, and how HLRS could

The iHURT focused on the computational challenges industry faces, with a special focus on the growing interest in solutions involving artificial intelligence. In addition to enabling academic research, the High-Performance Computing Center Stuttgart (HLRS) supports industry by making its supercomputing resources for simulation, machine learning, and visualization available for research and development. To better understand and address the specific needs of industrial HPC users, SICOS BW and HLRShosted the third annual Industrial HPC User Roundtable (iHURT) on December 3, 2019.

Importance of Data Transfer in the Use of High Performance Computing – 2019/07/12

Importance of Data Transfer in the Use of High Performance Computing One part of EXCELLERAT’s vision is to provide the engineering community with easy access to relevant services and knowledge around high performance computing. The keyword here is ‘Access’. The idea that HPC centers can offer data calculation and simulation as a service, and thus expand the use of HPC in the industry, is based on transferring data online to HPC centers and back – simple, secure, traceable and reproducible. The company SSC-Services  GmbH* (Germany) is the industrial partner in the EXCELLERAT project to cover the topics data management and transfer.

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
