摘要
Compared with F.E.M, Boundary Element Method (B.E.M) has some advantages. That is, unknowns are relatively small, and the discretization is only the boundary of the analytical model. However, the error with numerical integration cannot be accurately evaluated. In this paper, 3-D magnetostatic field is calculated using the reduced scalar potential method for two regions model; a current free iron region with linear and isotropic property and an air region including the source domain. A unstable computational error near the boundary is investigated from the view of the numerical integration and the discretizations. © 1990, IEEE. All rights reserved.
