Abstract

In this paper an improved placement of the integration surface for the integral equation in the hybrid finite element method—Dirichletboundary condition iteration (FEM-DBCI) method is achieved by selecting it as lying in the middle of the tetrahedral or hexahedralfinite elements. A better accuracy is obtained with respect to the case in which the integration surface lies along the element faces. Somenumerical examples are provided
