摘要
Abstract
A new computation method of electromagnetic field element free method (EFM) is proposed. EFM only needs the information of nodes. Furthermore, the nodes can be distributed on needs. The main advantage is that it can solve complicated problems with arbitrary shapes, which finite element method (FEM) can not solve effectively. For example, when computing the electromagnetic force on the close state and studying the problems with odd shaped working gap, bigger errors occurs using FEM, but with EFM this problem can be avoided. The theoretical foundation of EFM is moving least-squares (MIS) . Detailed research is conducted on some key problems, such as the selection of weight function, the selection of influence radii of nodes. And according to the theory of minimum of energy, penalty function is introduced in order to give boundary conditions.关键词
