Abstract : Dealing with numerous bodies in interaction, as occurring in granular media, requires larger and larger computational resources. To this end we develop a domain-decomposition-like method suited to discrete systems with diffuse non smoothness. A multiscale enrichment completes the numerical strategy with extra hope to bridge the gap between discrete and continuum models. The equilibrium of a tensegrity structure, closer to the continuous media case, is chosen to test this approach.
