虽然边界元法具有边界离散化的优点，但由于其密集的矩阵形式，对于大规模的3-D问题，其计算工作量和存储要求变得令人望而却步。计算n体问题，如带电粒子模拟，有类似的固有困难。本文利用快速多极子方法克服了这些困难，并将其应用于三维电子枪分析，其中涉及到求解边界元和n体问题。
Although BEM enjoys the boundary only discretization, the computational work and memory requirements become prohibitive for large-scale 3-D problems due to its dense matrix formulation. The computation of n-body problems, such as in charged particle simulation, has a similar inherent difficulty. In this paper, we use the Fast Multipole Method to overcome these difficulties and apply it to the 3-D analysis of electron guns, which involves both solving BEM and n-body problems.
