We will show in this presentation a new implementation of a multi-scale, multi-model coupling algorithm, based on the Arlequin framework. We propose a parallelization scheme for the construction of the coupling terms between the models, resulting into a scalable algorithm on large computer clusters. As an application example, we will consider a system composed by an homogeneous, macroscopic elasto-plastic model and an anisotropic polycrystalline material model.
