Recent developments in computational technology have enabled the analysis of increasingly complex and higher-dimensional problems with ease even on small or personal computers. At the same time, post-processing techniques also have undergone tremendous development, especially in the domain of scientific visualization, simulation and animation. The main goal of these developments is to assist in the estimation and evaluation of computational results and in understanding their physical meaning. For an easy undersatnding of the physical behavior of the eddy current field phenomena, therefore, visualization of the eddy current lines is somehow necessary. Using eddy current lines, the analyst can clearly understand the physical meaning of the analyzed eddy current field. In this paper, a new analytical method for computation of eddy current lines in 3-D space is proposed. The solenoidal characteristic of eddy current line, which results in eddy current lines becoming closed lines, is also successfully treated by means of edge finite elements. The procedure and examples to demonstrate the advantages of the proposed method are also presented.
