Solving Electric Field Problem with Finite-difference Method

LI Guo-sheng(College of Automation Engineering,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China)  
The origin of finite-difference method is introduced first,then its applications in electrostatic are discussed.It takes the physical model of aluminum cell whose field is discreted with FDM method for instance,the Matlab and C are used to calculate the electric potential of each node.Then,isopotential and electric field intensity lines are plotted.The influence of acceleration convergence factor to the speed of iterative method and the distribution of electric field under the sinusoidal boundaries are discussed.
