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.

New regional climate projections for metropolitan France

superadmin |  11 February 2021

Cerfacs collaborated with Météo France and the Institut Pierre-Simon-Laplace (IPSL) to produce the DRIAS climate dataset, which presents a wide range of possible climate changes for metropolitan France for three periods of the 21st century (2021-2050, 2041-2070 and 2071-2100) and three greenhouse gas emission scenarios.

New research group “Theory and Climate”

Mélanie ROCHOUX |  1 February 2021

CECI is involved in the development of a new research group (GDR for “Groupement De Recherche”) entitled “Theory and Climate”. This GDR aims at bringing together the entire community of theorists (mathematicians, physicists, computer scientists, data scientists, etc.) working on climate sciences, with the goal of developing and sharing innovative concepts and tools relevant for a better understanding of climate dynamics. This GDR is interdisciplinary and involves several CNRS research institutes as well as most of French organizations working in these fields. CECI plans to contribute to issues related to climate dynamics and applied mathematics such as data assimilation and machine learning. Moreover, there are strong links between this GDR and the LEFE-INSU actions, in which CECI researchers are active (LEFE-IMAGO and LEFE-MANU actions). More information here:Read more
