DC capacitor simulation by the boundary element method. When the direct current (DC) metallized thin film capacitor is fully charged the electromagnetic fields can be considered to have reached a steady state in which the governing equation is Laplace’s equation. It is the computational analysis of the electrostatic state that is considered in this paper. The capacitor is modelled as a stack made up of infinitesimally thin layers of metal on polymer. An integral equation method from the BEMLAP package (url{} (Introduction to the Boundary Element Method for Scientists and Engineers: The BEMLAP Fortran Library for Laplace Problems)) for modelling the electric field, based on the methods described by extit{S. M. Kirkup} [Adv. Comput. Math. 9, 391--409 (1998; Zbl 0913.65102)]. The method is applied to a typical capacitor structure and encouraging results are obtained.
