三维中子输运分流再平衡加速及其并行算法
Parallel partial current rebalance algorithm for neutron transport simulation
摘要
Abstract
To accelerate neutron transport calculation using discrete ordinates method, this paper presents a parallel partial current rebalance(PCR) algorithm based on domain decomposition, which is coupled with algebraic multigrid solver.The parallel PCR algorithm has been integrated in JSNT software and its correctness and effectiveness have been verified by typical critical and extraneous source calculation.In the pressure vessel shielding calculation of the pressurized water reactor in China, the iteration number and total computing time are decreased by more than 3 and 2 times respectively, the parallel efficiency on 1024 cores is 42.8%.关键词
