摘要
本文从刚度矩阵的元素形成规律入手,导出了便于对场域某一部分进行重复计算的矩阵分块解法,该方法大大提高了局部场域重复计算的效率,从而提高了优化的效率,另外,该方法克服了边界移动导致单元畸形带来的失真。
Solving process with matrix partition, which is suitable for repeated calculation in a sub-field of the electric field, is formed by formation rule of stiffness matrix. The method can improve the calculating efficiency for optimization of electric field, and it can overcome the inaccuracy from abnormal elements caused by field boundary.
