Décomposition de domaine en dynamique granulaire par éléments discrets et application au ballast ferroviaire
Résumé
Large granular dynamical systems simulation requires the help of parallel computations. Domain decomposition methods (DDM), classically used for continuum media is extended herein to a discrete element model. Parallelization of the LMGC90 code, developed in LMGC, for a parallel distributed memory environment is of interest to the application to railway track ballast, at SNCF. Here, we focus on two different versions of a DDM, within the framework of LMGC90 code.
