摘要

摘要: ARES是基于离散纵标法开发的一维、二维、三维多群各向异性散射屏蔽输运程序系统，应用于核装置的屏蔽计算和分析。采用菱形差分、theta权重、非连续有限元多种空间离散策略，离散求积组自适应选择，能处理多种边界条件和屏蔽源项。采用首次碰撞源法消除或减轻孤立点源、大空腔模型、强吸收介质等屏蔽问题中的射线效应难题。加速模块采用扩散综合加速、角度多重网格、区域分解的MPI并行，能对不同屏蔽计算模型产生有效的加速效果。采用基准例题和程序对标的方法对部分模块进行初步验证。

Abstract: ARES is a multi-group of anisotropic scattering transport code based on discrete ordinates method. It is primarily used for the nuclear device’s shielding calculation and analysis in the case of one-dimension, two-dimension and three-dimension. A variety of options allow spatial variables to be dispersed by the diamond difference, theta weight or discontinuous finite element method. The quadrature set can be adaptively selected. Variety of boundary conditions and sources can be treated. First collision source method was used to eliminate or mitigate the ray effect. The acceleration module consists of diffusion synthetic acceleration (DSA), angular multigrid and MPI parallel of domain decomposition. The preliminary verification for part module of the shielding code has been done by benchmark and reference code.
