摘　　要：大型铝电解槽的数值仿真采用有限元分析方法,伴随着有限元模型的大型化、精细化,其对有限元计算速度提出了更高的要求。为此,本文将并行计算应用于铝电解槽电场仿真计算中,针对决定并行计算效率的区域划分环节,结合铝电解槽模型特点引入ANP(Al-NASRA and NGUYEN)算法,并和常用的多层次方法进行比较。数值分析结果表明:基于ANP算法的有限元并行计算方法在面对铝电解槽这类复杂三维模型时能够取得良好的划分结果,进而得到较优的并行计算加速比。The finite element analysis method is applied in the numerical simulation of large-scale complicated structures, such as aluminum reduction ceU. Along with the larger and more detailed trend of Finite element model, finite element analysis requires higher performance on calculation speed. Therefore parallel computing is applied to the calculation process of the finite element analysis. Because the procedure of domain decomposition determines the efficiency of parallel computing, ANP（A1-NASRA and NGUYEN） algorithm is introduced by taking the characteristics of aluminum reduction cell model into account. And it has been compared with the popular multilevel partitioning scheme. Experiment results show that ANP-based parallel finite element analysis has the more reasonable domain decomposition in aluminum reduction cell model, therefore it can obtain the better speedup ratio of parallel calculation.
