Cerfacs Enter the world of high performance ...

PUMA Challenge

The PUMA challenge addresses the unsteady multi-physics simulations over a whole aircraft in realistic flight conditions. The goal is to go further in understanding the unsteady turbulent phenomena using the Large Eddy Simulation (LES). Various numerical approaches will be evaluated and compared (Finite Volume, Lattice Boltzmann and Spectral Difference). Of course, large scale configuration demands many grid points and  playing with a massively parallel environment is the key point.

Unsteady multi-physics simulation around a whole aircraft taking realistic flight conditions into account. The unsteady variations of the flow around the aircraft are simulated with LES (Large Eddy Simulation).

Brigitte Yzel |  31 May 2022

Catherine LAMBERT, President of Cerfacs, has been promoted to the grade of officer in the national order of Merit, on the proposal of Mrs. Frédérique Vidal, Minister of Higher Education, Research and Innovation. Antoine PETIT, President and CEO of the CNRS, presented the insignia to Catherine LAMBERT during a ceremony that brought together many actors from the space, aeronautics, environment and digital sectors. Antoine PETIT: "Catherine's interpersonal skills, her ability to step back and understand very different environments (research, industry, politics) in order to develop a collective vision are the hallmarks of her career. Catherine is one of those people with whom you naturally feel confident, with whom you want to build something that goes beyond all of us to go further. With this honor, the Cerfacs teams are also rewarded.Read more
