A New Parallel Algorithm of DSMC Method

AbstractA new parallel algorithm of DSMC method with dynamic load balance implementation was introduced using MPI standard library. The parallel efficiency of the two kinds of parallel modes, peer-to-peer mode and master/slave mode, were investigated, respectively. The key points of implementation in unstructured DSMC code using peer-to-peer parallel mode were analyzed. Validity about this method was investigated by analyzing blunt cone flow field. The numerical results confirm the feasibility of method mentioned above
