In view of the repetitive modeling shortcoming of the finite element analysis software ANSYS exisited in large-scale simulation

the VC is taken as as a platform to perform the secondary development of ANSYS parametric design language（APDL）

set up a visual operation interface

call ANSYS in the background to complete automatically the parametric modeling and finite element simulation analysis of the iron core reactor with purpose of effectively shortening design period of product. Then

both accuracy and applicability of the system are verified by comparison of such two inductive methods as magnetic circuit method and energy perturbation method. Finally

a kind of method for batch processing of finite element simulation is proposed and

on this basis

a total of 132 times of three-dimensional nonlinear transient magnetic field simulations are performed and the influence of non-sinusoidal excitation after superposition of harmonics and fundmental waves containing different contents

numbers and phase on the magnetic filed of the core reactor

which provides reference for mastering the distribution law of magnetic field of core reactorunder the action of harmonics.
