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 the high-fidelity solver 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 (Large Eddy Simulation) code dedicated to unsteady compressible flows in 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. Its spatial accuracy on unstructured hybrid meshes is 3. AVBP 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 (SAFRAN AIRCRAFT ENGINES, SAFRAN HELICOPTER ENGINES, ARIANEGROUP, 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. AVBP was the baseline code for the European Research Council advanced grant on thermoacoustics lead by IMFT and CERFACS: INTECOCIS (http://intecocis.inp-toulouse.fr).


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. Jaguar is developed jointly by CERFACS and ONERA to build a high-order tool for combustion and more generally for energetic applications.


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.

New supercomputer opened at Cerfacs

superadmin |  16 May 2018

Since the beginning of May 2018, a new supercomputer named Kraken has been setup to reinforce Cerfacs' simulation capabilities. With a peak performance of 315 Tflop / s this new computer provided by Lenovo is now available to all of Cerfacs' researchers in addition to the Nemo computer. The...Read more
