摘要：

In order to evaluate the most suitable method of analysis (A-phi or T-OMEGA-method) and finite element (nodal or edge element) for a given problem, features of each method and element have been investigated. The accuracy, the computer storage and the CPU time of each method and element are compared with each other for the 3-D non-linear magnetostatic model (TEAM Workshop Problem 13) and the 3-D eddy current model (IEEJ model). The flux and eddy current densities calculated are compared with those measured. It is shown that the accuracy and the CPU time of the edge element are better than those of the nodal element. The A method is better than OMEGA-method for non-linear problems from the viewpoint of convergence characteristics of non-linear iterations.
