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).


Swings oceanographic campaign

Christophe Cassou, a researcher at the Cerfacs/CNRS joint laboratory (CECI: Climate, Environment, Couplings and Uncertainties) will take part in the Swings oceanographic campaign, involving 48 scientists and led by two CNRS researchers. It will take place in the Southern Ocean on board the Marion Dufresne II of the French Oceanographic Fleet (FOF), operated by Ifremer, from 11 January to 8 March. 2 months sea explore southen oceansRead more
