Cerfacs Enter the world of high performance ...

Computational Fluid Dynamics Softwares

The CFD team at CERFACS develops a wide range of software tools for fluid flows, with or without chemical reaction. The major codes are listed below:

Explosions in building

Explosions in building: LES with AVBP on an INCITE machine. 1 billion cells. A premixed flame propagates from the left to the right side of the picture and increases speed when it meets obstacles and generates turbulence. See many more examples and movies here. in the field of combustion and turbo machinery 



AVBP is a LES code dedicated to complex geometries. It is applied to combustion chambers, turbo machinery, safety analysis, optimization of combustors, pollutant formation (CO, NO, soot), UQ analysis. AVBP uses a high-order Taylor Galerkin scheme on hybrid meshes for multi species perfect of real gases. It is a world standard for LES of combustion in engines and gas turbines, owned by CERFACS and IFP Energies Nouvelles. It is used by multiple laboratories (IMFT, EM2C, TU Munich, Von Karmann Institute, ETH Zurich, etc) and companies (SNECMA, TURBOMECA, Airbus Safran Launchers, Ansaldo, HERAKLES, etc). It is also a usual benchmark code by many computing centers to test their machines. CERFACS collaborates with INTEL through an IPCC  to continuously increase the performances of the solver.


JAGUAR is a new high-order method developed at CERFACS and based on spectral difference techniques. It can offer very high orders of accuracy (4 to 8) on arbitrary meshes.


elsA is a software owned by ONERA and co developed for certain aspects by CERFACS. For example, for aircraft aerodynamics or for turbo machinery, CERFACS develops certain aspects of elsA and applies this tool to various design problems.



CECI Contribution to CNRS’ “Petit Illustré” on Complex Systems (CNRS Edition)

ROGEL |  12 October 2017

CECI (Cerfacs, CNRS) and IMFT are both working on numerical modelling of the processes causing river flooding and their uncertainties. A common contribution on this subject, signed by Sophie Ricci and Hélène Roux, appears in Vol. 34 of the "Petit Illustré" collection, edited by CNRS.Read more

CERFACS was present at the European Researcher Night 2017 at Toulouse

thual |  1 October 2017

"Can we get an engine, an airplane or the entire Earth into a computer?". Such was the catchy title of the CERFACS stand  Friday September 29th, for the "European Research Night" whose theme was "Impossible". A hundred people at the "Quai des Savoirs" in Toulouse took a close interest in the...Read more
