[en] In this work, a strategy for the parallelization of a two-way CFD-DEM coupling is investigated.
It consists on adopting balanced overlapping partitions for the CFD and the DEM domains,
that aims to reduce the memory consumption and inter-process communication between CFD and DEM.
Two benchmarks are proposed to assess the consistency and scalability of this approach,
coupled execution on 252 cores shows that less than 1\% of time is used to perform inter-physics data exchange.
