Cerfacs Enter the world of high performance ...

Aerodynamics

Introduction

Numerical aerodynamics is a main topic for CERFACS. The CFD team develops numerical methods and tools that are used for academic cases but  more particularly in realistic aeronautical configuration : civil aviation, turbomachinery, helicopters or rockets.

This leads to simulate large computational domains and to use massive parallel computing platforms. Their efficient use is a fundamental CERFACS feature.

Research directions

The turbulence resolution is at the heart of our activity. For this, different approaches are used (RANS/URANS/LES/DNS) on multi-physics applications (aerocoustics, aerothermics or aeroelasticity). In addition to classic solvers and in order to prepare the next CFD solver generation, CERFACS invests on new approaches such as the very-high order methods or the Boltzmann method on lattices (LBM : Lattice Boltzmann Method).

This appears in the use of numerous solvers : elsA (http://elsa.onera.fr), AVBP, LaBS and Jaguar.

This diversity of approaches and solvers allows CERFACS to have an enlarged vision of the CFD world.

Collaborations

All the research activities are led in collaboration with numerous research centres (ONERA, Marseille University, Renault, Cenaero, IMFT, ECL, PPRIME, Sherbrooke University, DLR, von Karman Institute, Leceister University) as well as industrials ((Airbus, Airbus Hélicoptère, Airbus Defence and Space, Snecma, Turbomeca, SAFRAN Tech) through national or European programs.

Staying connected enables CERFACS to be at the forefront of what is being done in the numerical or aerodynamical simulation field.

Continuity of activity of the Cerfacs during the Covid-19 pandemic

superadmin |  20 March 2020

On Monday 16 March 2020, in the context of the rapidly evolving COVID-19 epidemic, Cerfacs decided to reorganize its activities by implementing a Business Continuity Plan (BCP) and deploying teleworking facilities for all its employees. All staff members thus continue to carry out their full mission.Read more


A fiery wakeup call for climate science

superadmin |  26 February 2020

The extent of the recent wildfires in Australia significantly exceeded the projections of any member of the multi-model CMIP archive.  This highlights how current multi-model ensembles may be under-representing the risks of natural disasters under climate change.  Limited coupled system process representation in most models coupled with a lack of parameter uncertainty exploration means that some risks are not explored by the existing international multi-model framework.  This calls for a reassessment of how to focus climate model development on providing robust risk quantification for those impacts which most directly affect society.
