Abstract

Abstract

The auto-modeling of an arbitrary shaped conducting body is studied by the software AutoCAD firstly, and the surface model of the conducting body is achieved on base of many basic triangle meshes. Then the basic theory of the solution for the capacitance of an arbitrary shaped conducting body is presented by method of moment, and the closed-form of diagonal matrix elements and the numerical result of off-diagonal matrix elements are deduced. Finally, some examples of two-dimensional and three-dimensional bodies are given, at the same time the Richardsons extrapolations of these numerical results are calculated. The results agree well with the corresponding close-form and the reference value in literature. Thus the methods accuracy and high efficiency are illuminated.
