The primary objective of the proposed research is to develop a dynamic domain decomposition strategy to achieve an effective parallel implementation of combined finite/discrete approaches for large-scale engineering problems involving multi-fracture and multi-contact phenomena. Issues to be investigated include general implementation strategies, reviewing and parallelisation of contact detection approaches, enhancement of graph representation models for discrete objects, selection of effective parallelised graph (re-)partitioning methods, and development of a dynamic load imbalance detection and re-balancing scheme. The implementation is intended to be general for both shared and distributed memory parallel hardware architectures by the use of the message passing interface, MPI. In particular, it is felt essential that the parallel implementation be undertaken on the latest generation of low cost parallel desktop machines, such as PC clusters, in order to bring the computational technology developed within the reach of SMEs. The parallel finite/discrete analysis system to be developed in this project will significantly reduce the computational time required so that many complex practical problems, particularly arising in mining and processing engineering can be numerically simulated within a reasonable time scale. This will then improve the understanding of the physical phenomena concerned.
