A dynamic domain decomposition strategy is proposed for the effective parallel implementation of combined finite/discrete element approaches for problems involving multi-fracture and multi-contact phenomena. Attention is focused on the parallelised interaction detection between discrete objects. Two graph representation models, are proposed and a load imbalance detection and re-balancing scheme is also suggested. Finally, numerical examples are provided to illustrate the parallel performance achieved with the current implementation.
