Parallelised finite/discrete element simulation of multi-fracturing solidsand discrete systems

This paper outlines a dynamic domain decomposition-based parallel strategy for combined finite/discrete element analysis of multi-fracturing solids an d discrete systems. Attention is focused on the parallelised interaction de tection between discrete objects. Two graph representation models for discr ete objects in contact are proposed which lay the foundation of the current development. In addition, a load imbalance detection and re-balancing sche me is also suggested to enhance the parallel performance. Finally, numerica l examples are provided to illustrate the parallel performance achieved wit h the current implementation.
