Abstract

Based on the conjugate and harmonic properties of electric potential and flux, the nodal electric flux is numerically calculated through the curve integral of electric displacement, which is solved by numerical differentiation of the nodal electric potential calculated by the finite-element method. Therefore, the electric force line (actually the line of electric displacement or electric equi-flux line) may be plotted. The proposed algorithm has been made into a postprocessing code and put in to SEF2D, an effective finite-element software package for the computation of 2-D electrostatic fields. Four examples show that it is an effective postprocessing algorithm
