This model is used to simulate granular media where every grain is identified separately, generating very time-consuming simulations. First, we show a data structure based on a triangulation which defines a neighbourhood of each grain. This allows to save computing time. Then we explain how to distribute data and work on the processors and give some preliminary results.text::journal::journal article::research article
