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).


Medal of the Academy of Air and Space: 3 CERFACS researchers awarded !

The Air and Space Academy awarded Carlos Pérez Arroyo, Gabriel Staffelbach and Jérôme Dombard with the Vermeil medal 2022, to honor the excellence of their work in the realization of the FULLEST project, the first high-fidelity simulation of an aircraft engine. Thanks to PRACE for awarding the access to the Joliot-Curie supercomputer (GENCI hosted at CEA/TGCC) and to DGAC for the funding of the ATOM project (No 2018-39) led by SAFRAN Tech. FULLEST also benefited from developments done in European projects:  EXCELLERAT (H2020 823691) and EPEEC (H2020 801051).  Read more


CERFACS |  4 July 2022

CERFACS will participate to the Paris meeting dedicated to the memory of Roland Glowinski from July 5th to 7th. Thierry Poinsot will present the advances of HPC in the field of energy and combustion. Roland Glowinski was CERFACS direcfor for 3 years in the 90s and largely shaped present activities of our research center.Read more
