Cerfacs Enter the world of high performance ...

PUMA Challenge

The PUMA challenge addresses the unsteady multi-physics simulations over a whole aircraft in realistic flight conditions. The goal is to go further in understanding the unsteady turbulent phenomena using the Large Eddy Simulation (LES). Various numerical approaches will be evaluated and compared (Finite Volume, Lattice Boltzmann and Spectral Difference). Of course, large scale configuration demands many grid points and  playing with a massively parallel environment is the key point.

Unsteady multi-physics simulation around a whole aircraft taking realistic flight conditions into account. The unsteady variations of the flow around the aircraft are simulated with LES (Large Eddy Simulation).



A bronze medal to Cerfacs for “Allons-Y À Vélo” !

CERFACS |  26 July 2021

A bronze medal to Cerfacs for "Allons-Y À Vélo" ! Cerfacs is on the podium for its cycling regularity during the "Allons-Y À Vélo" period (May 25 - June 25) in its category (100-500 employees).During this period, 37% of Cerfacs employees came to work by bike during at least 4 consecutive days. "Allons-Y À Vélo" is a campaign organised by the association "2 Pieds 2 Roues" and "La Maison du Vélo de Toulouse" to promote the use of the bicycle for every day travels; all details can be found on allonsyavelo.le-pic.org . Cerfacs encourages its employees to use their bicycle to come to work as they benefit from the bicycle mileage allowance (FMD for Forfait Mobilité Durable) of up to 500 Euros per year.Read more

The H2OPE project wins the prize Joseph Fourier 2021

CERFACS |  26 July 2021

The H2OPE project wins the prize Joseph Fourier 2021 The prize, launched by Atos and GENCI, aims to reward the work of researchers, academics and industry in two strategic areas: Advanced Computing (HPC, Quantum, Edge) and Artificial Intelligence, and, in the 2021 edition , gives particular importance to Decarbonation. The 1st Prize was awarded to the H2OPE or “H2OPErability for safe and clean gas turbine engines” project from CERFACS in Toulouse. This project aims, via the LES AVBP code, to model at high resolution a mixed combustion process associating conventional fuels with hydrogen (bi-fuels) as one of the most promising technical solutions to achieve "net zero emissions" of CO2 in the industrial sector. It was presented by Walter Agostinelli, Davide Laera, Laurent Gicquel, and Thierry Poinsot. Press release :Read more
