In this paper, the accuracy of the integral equation of the hybrid finite-element-method–Dirichlet boundary condition iteration methodis improved for the computation of open boundary electrostatic fields. This is achieved by selecting the integration curve (or surface) as lying in the middle of the triangular (or tetrahedral) elements. A notable improvement in accuracy is obtained compared with selecting the integration curve (or surface) as constituted by element sides.

Abstract
In this paper, the accuracy of the integral equation of the hybrid finite-element-method–Dirichlet boundary condition iteration methodis improved for the computation of open boundary electrostatic fields. This is achieved by selecting the integration curve (or surface) as lying in the middle of the triangular (or tetrahedral) elements. A notable improvement in accuracy is obtained compared with selecting the integration curve (or surface) as constituted by element sides.File in questo prodotto:
