Parallel Numerical Computing of Finite Element Model of Conductors and Floating Potentials

In computational electromagnetics, parallel computing is more and more studied to deal with large-scale problems which are not able to execute by single PC. Many parallel computing example for electrostatic had been reported. But for electrostatic problems in which floating conductors exist, the realization of parallel is not reported. In the electrostatic model that contains floating conductors, the surfaces of such conductors represent equipotentials but do not constitute a Dirichlet boundary condition. So the partition of such model is difficult to control. This paper presented a way for the partition of the model containing floating conductors and a method that can be used to solve such problem through parallel system. An example which contained three floating conductors was computed by using the method introduced in this paper, the result was displayed and compared with conventional finite element model, the validity of the method is proved.
