2013 Annual Report of the Project “Algorithms and Software of Particle Transport to Support the Coupling of Multi-physics”

"支持多物理耦合的粒子输运算法与软件"属于国家973计划项目"适应于千万亿次科学计算的新型计算模式",由北京应用物理与计算数学研究所、清华大学、国防科技大学承担。该课题围绕实际重大需求中粒子输运与流体力学过程的耦合,开展了流体力学计算、辐射扩散计算和粒子输运计算的数值算法研究。该文报告重点阐述SN中子输运多级并行算法、中子输运方程基于介质分区的自适应计算方法和辐射流体问题的量身定做有限点方法。

The project ＂Algorithms and Software of Particle Transport the sub-project of the 973 project ＂New Paradigms for Peta-scale Tsinghua University and National University of Defense Technology. to Support the Coupling of Multi-physics＂ is Scientific Computing＇and is taken on IAPCM, The project has accomplished the research of the numerical algorithms for computing fluid dynamics, radiation diffusion, particle transport, surrounding the coupling of particle transport with fluid dynamics for actual important requirements. This paper is the annual report of the project about the main developments for the year 2013, which focuses on the multilevel parallel algorithm and the adaptive method for neutron transport equations as well as the tailored finite point method for radiation diffusion problems.
