Abstract：The project“Algorithms and Software of Particle Transport to Support the Coupling of Multi-physics”is the sub-project of the 973 project “New Paradigms for Peta-scale Scientific Computing”and is taken on IAPCM， Tsinghua University and National University of Defense Technology. 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.
Key Words：Fluid dynamics；Radiation diffusion；Particle transport；Multilevel parallel；Adaptive method；Tailored finite point method
