Theoretical and numerical combustion is a central field at CERFACS. With highly precise unsteady simulations, the CFD team replicates combustion in numerous systems going from academic experiments in laboratories’ flames to motors of helicopters, rockets, planes, cars, also including accidental explosions in buildings or chemical reactions in the refining field.


High-fidelity simulations

The first objective of the combustion team at CERFACS, is to keep the highest possible precision in terms of turbulence description or chemical kinetics, which are the most critical elements of a combustion simulation code.

This leads to large size codes using mesh with billions of points as well as simulations which need the biggest current operating computers (hundreds of thousands of cores).


The Cerfacs codes as a world reference

The CERFACS codes in combustion (the most famous being AVBP) are the world reference in the field and are used in numerous laboratories (e.g. IMFT in Toulouse, EM2C in Paris, CORIA in Rouen, TU in Munich, IFP Energies Nouvelles in both Rueil-Malmaison and in Solaire, ETH in Zurich, Institut von Karman in Belgium, etc.). AVBP is particularly efficient for compressible reacting flows. Today, it is associated with another code (YALES2) that Coria (Rouen) developed for the low Mach flows. These two codes are also used by several manufacturers (SNECMA Villaroche, SNECMA Vernon, SAFRAN Tech, Turbomeca, Ansaldo, Renault, PSA, Herakles, AREVA) which makes the AVBP/YALES2 community the biggest combustion team in the world.




Tribute to Françoise Chatelin

  Tribute to Françoise CHATELIN   Virtual & Face to Face event @ Cerfacs 14 October 2021, CERFACS, Toulouse (France) 2 pm - 6.30 pm   Cerfacs is organizing a half scientific day on Thursday October 14, 2021 in tribute to Françoise Chatelin who left us prematurely on May 14, 2020   After graduating from the Ecole Normale Supérieure in Paris (1960-63), and her PhD in Mathematics at Grenoble University (1971) , Françoise Chatelin led with worldwide recognition her research in many areas, from spectral theory for linear operators in Banach spaces and finite precision to Dickson algebras. Professor Chatelin taught at the Universities Grenoble 2 - Pierre Mendès-France and Paris 9 - Dauphine before moving to Toulouse in 1996. She became Emeritus Professor in 2015. She was a visiting researcher at Berkeley and Stanford Universities, IBM San Jose (Ca) and Yorktown Heights (NY). For almost a decade, she was a scientific manager in Industry (in charge of intensive computing) first at the Centre Scientifique IBM France in Paris (1985 -1992) and then in the Central Research Lab of Thales (known as Thomson-CSF at that time) near Paris (1992-95). Françoise Chatelin was Head of the Qualitative Computing group at the Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (Cerfacs) in Toulouse, France. Professor Chatelin has authored four books; the first three are now classic references available from SIAM. Her second book Valeurs Propres de Matrices (Masson, Paris, 1988) has received the IBM - France prize for « Best Scientific and technical publication 1988 ». Beyond her scientific contribution, Françoise Chatelin played a structuring role on research at CERFACS through multiple thesis on innovative topics. This event is devoted to the human and scientific tribute of her life. As a faithful image of the active and passionate woman that...Read more

CERFACS is involved in the NextSim project

CERFACS |  19 July 2021

The primary objective is to increase the capabilities of Computational Fluid Dynamics tools on extreme-scale parallel computing platforms for aeronautical design. The Kick-Off Meeting took place on 12 March 2021. This project has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement N° 956104. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and Spain, France, Germany.
