Abstract

The article deals with solution of magnetostatic field problems by boundary element method and its accelerating based on fast multipole method. This approach can significantly reduce the computational cost and solve problems with higher degree of freedom. Due to symmetric Galerkin formulation, this method can be used together with the finite element method for solving nonlinear problems of magnetostatics. Numerical experiments results demonstrating the effectiveness of this approach are presented.

Keywords: boundary element method, finite element method, magnetostatics, incomplete scalar magnetic potential, spherical harmonics
