This paper presents a numerical analysis for computation of free space capacitance of different arbitrarily shaped conducting bodies based on the finite element method with triangular subsection modeling. Evaluation of capacitance of different arbitrary shapes is important for the electrostatic analysis. Capacitance computation is an important step in the prediction of electrostatic discharge which causes electromagnetic interference. We specifically illustrated capacitance computation of electrostatic models like unit cube, rectangular plate, triangular plate, T-shaped plate, sphere and two touching spheres. Numerical data on the capacitance of conducting objects are presented. The results are compared with other available results in the literature. We used the COMSOL Multiphysics software for the simulation. The models are designed in three-dimensional form using electrostatic environment and can be applied to any spacecraft circuit modeling design. The findings of this study show that the finite element method is a more accurate method and can be applied to any circuit modeling design.

The capacitance evaluation of conducting bodies is an importance step for prediction of electrostatic discharge problem. In this paper an attempt has been made for the evaluation of charge distribution and the capacitance of conducting surface. There are different methods such as method of moment (MOM), Finite element method (FEM), Finite difference method (FDM), Charge Simulation method (CSM), point matching method and Surface charge method. In this paper the MOM based on the pulse basis function and point matching is used. The integrand is divided into a regular and a singular part. The MOM is based upon the transformation of an integral equation, into a matrix equation by employing expansion of the unknown in terms of known basis functions with unknown coefficients such as charge distribution and hence the capacitance is to be determined. This paper reviews the results of computing the capacitance-per-unit length of square plates. Index Terms-Capacitance, electrostatic discharge, point matching, rectangular subdomain, method of moments, finite element method.
