The Coupled NBEM and FEM for Three-Dimensional Exterior Problem with a Prolate Spherical Artificial Boundary

摘要：

In this paper, based on the natural boundary reduction, we discuss a coupled NBEM and FEM for three-dimensional exterior harmonic problem. We express the artificial boundary condition on the prolate spherical artificial boundary in a series form explicitly. The error estimates are related to the mesh size, the terms after truncating the infinite series, and the location of the artificial boundary.
