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 numerical simulation of large-scale aluminum reduction cell adopts the finite element analysis method. With the enlargement and refinement of the finite element model, it puts forward higher requirements for the finite element calculation speed. Therefore, in this paper, the parallel computing is applied to the electric field simulation of aluminum reduction cell. In order to determine the area division of parallel computing efficiency, the ANP (Al-NASRA and NGUYEN) algorithm is introduced in combination with the characteristics of aluminum reduction cell model. Method to compare. The numerical results show that the finite element parallel computing method based on ANP algorithm can get a good partition result in the face of the complex three-dimensional model such as aluminum reduction cell, and then get better parallel computing acceleration ratio.
