In this collaboration, IRSN, LMGC and IFPEN joined their efforts towards the development of three-dimensional and parallel efficient numerical methods for the direct numerical simulation of particulate flows. Essentially, we contructed the first version of the PeliGRIFF code based on the Pelicans platform, a C++ application framework for the solution of PDE and initial boundary value problems on meshes. Pelicans is developed and maintained by IRSN and is freely available under the Cecill-C licence. PeliGRIFF is the result on the re-implementation of the IFPEN prototype code for particulate flows named GRIFF (GRains In Fluid Flows) based on Pelicans. In particular, the coupling of the Navier & Stokes with the particles motion relies, at the code architecture level, on a plug-in technique, which permits to connect various granular dynamics solvers. In particular, PeliGRIFF was coupled to the Non-Smooth Contact Dynamics code LMGC90, from the LMGC laboratory of Montpellier, and used to investigate to the dynamics of sub-marine avalanches.
