GPU based parallel method for dynamic collision grid DSMC. Journal of Frontiers of Computer Science and Technology, 2013, 7(5) ：472-479. Abstract: The direct simulation Monte Carlo (DSMC) method is a powerful computational tool in the field of rarefied gas dynamics. However, there are two main shortages in DSMC method: one is complex gridding processing, the other is large time consumption. The dynamic collision grid DSMC method generates collision grids adaptively according to the flowfield, which overcomes the first shortage. For the other shortage, using compute unified device architecture (CUDA) to write parallel program, the dynamic collision grid DSMC method is ported to graphic pro- cessing unit (GPU) to reduce computing time.
