APPLICATION OF VISUALIZATION IN THE EQUIVALENT SOURCE METHOD

The number and position and order of theequivalent sources employed have influence over the solution when the equivalent source method is applied to solve anelectro (or magneto) static filed. Based on the display of the tridemetional graph and the isopotential graph of the solution, the influence is studied in this paper first time. The rule of determining the number and position of the equivalent sources is given. There is a different order range to every equivalent source when the number and position of the equivalent sources employed have been determined. Changing the order from the range properly will decrease the error of the solution, but taking the order out of the range will distort the field of the solution. It would be audio-visual and exact to distinguish the situation of the field with the help of visualization of the solution. The method, which combining the visualization of the solution with the calculation error at the check dots on the borderlines of the filed to determine the equivalent sources(the number andposition and order), will make the solution reliable, more accurate and efficient.
