Abstract :
The computational tool described is based upon three-dimensional geometric modeling and electrostatic charge simulation, for determination of capacitance matrices between three-dimensional bodies, including the influence of a ground plane. These matrices provide a means of computing potential and electric field distributions between approaching bodies, and thus determining relative probabilities of electrostatic discharge. Also, energy storage computations before and after a discharge provide a means for estimating the relative severity of the event. The tool is used to compute capacitance matrices for a simple model of a human body with arm and finger approaching another object.<>
