| Abstract: | 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. |
