The visualization of electric force lines in two-dimensional electric field computation

摘要

An algorithm for the visualization of the electric force lines is discussed. Based on the nodal potentials calculated by the conventional finite element method, the boundary conditions of the electric flux are determined by the integral of the electric displacement along all conductors. The finite element equations of the electric flux for two-dimensional fields in order to avoid the infinity of the vector electric potential at the symmetrical axis. The nodal electric fluxes are calculated and the smooth electric force lines are visualized. Some examples show that this algorithm is very effective.
