摘要:
At present, the finite element method has been widely used in electrical engineering;value has an absolute advantage in the field of solving the problem of position in the electromagnetic boundary. From the view of historical development, the electromagnetic boundary value problem solving are graphical method, simulation method, analytical method and numerical calculation of four kinds of methods. Finite element method is introduced to this field has developed rapidly. Before the numerical calculation method, although has done a lot of work, but by the results, the electromagnetic boundary value problem solving range is very limited, numerical calculation method is made up this point. © 2014, Jiaxian Li.
