Estimation of capacitance of different conducting objects using triangular subsection

In this paper finite element method (FEM) has been used to obtain the accurate and efficient computation of capacitance of different conducting bodies like cylinder, cube, cone, sphere, pyramid and tetrahedron. The surfaces are discretized using triangular subsections. For each of these objects, aseries of values of the number of N segments has been used. FEM is better method than Finite Difference Method and Method of Moment as it is easy to apply to complex region and it is possible to solve different types of problem. This paper presents the results for capacitance of different conducting shapes. The obtained results are compared with previous related works. The use of FEM results in a highly accurate solutions with significant savings in computation time and memory requirements.
