摘要
阐述无网格方法(Meshless Method)及其在静电场分析中的基本原理。权函数的选择是此方法的核心,比较了不同权函数对计算速度和精度的影响。通过对二维静电场模型的分析,依据权函数选取的一般性原则,得出各种权函数中参数选取的范围,并找出了适合静电场分析的权函数。
The meshless method and its application issues in electrostatic field computation are presented. The choosing of the weighted functions is the key procedure. The computing speeds and precisions were compared under the different weighted functions. The 2D electrostatic field models was analyzed. The parameters' range of each weighted functions and the adaptive weighted function for solution of electrostatic field were given.
