Abstract
This paper proposes a mesh-less numerical analysis method employing magnetic moment method and particle method for magnetic fluid motion and magnetic phenomena. A basic idea in this method, the magnetic fluid motion is calculated by particle method, the magnetic field distribution and magnetic forces on the each particle are analyzed by magnetic moment method. The magnetic moment method analyzes magnetic field by dividing only ferromagnetic materials into fine elements. In this case, the elements of ferromagnetic materials are replaced with particles in particle method. The method not used calculation points on air and mesh for analyzing magnetic field. Therefore, reshaping of mesh on moved and divided fluids is not required, the analysis is robust over shift of topology. In this paper, an algorism of coupling the methods and analyze result of basic models are shown.
