Abstract

Mathematical simulation of electron-optical systems often requires high accuracy of electric and magnetic field calculation and smoothness of its results in the entire computational volume, not just near the symmetry axis. This requirement is necessary to construct aberrational series with respect to an arbitrary principle trajectory. To solve this problem, we propose an effective method for modeling non-linear magnetostatic systems. The method is based on decomposition of the computational domain into three parts, in which we employ different calculation approaches: the finite-element method and the boundary element method. Solution joining at the subdomains' boundaries is guaranteed by the use of common iteration procedure of minimizing the energy functional. The developed method allows calculating magnetic field with higher accuracy and less calculation difficulties.
