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

An algorithm for the visualization of the electric force lines is discussed . Based on the nodal potential; calculated by the conventional finite eleme nt method, the boundary conditions of the electric flux are determined by t he integral of the electric displacement along all conductors. The finite e lement equations of the electric flux for two-dimensional fields are derive d. Especially for the axial symmetrical field, a new interpolation function is defined 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 litres are visualized. Some examples show that this a lgorithm is very effective.
