Electromagnetic field distribution calculation program, and the electromagnetic field distribution computing device

摘要

the electromagnetic field distribution calculation method capable electromagnetic field analysis with high precision, the electromagnetic field distribution calculation device, and an electromagnetic field distribution calculation program even if the metal structure comprises a metal sheet structure. The electromagnetic field distribution calculation method of the present invention, the step of dividing the metallic elements of the metal structure surface, is set as a variable loop current flowing through the metal element on the metal elements on sent from the alternating magnetic field source Using calculating as an external magnetic flux density and magnetic flux density, and a loop current and the external magnetic flux density, was derived for each metal element equations normal component of the magnetic field in the metal element is 0, the metal structure If the body includes an aperture, the step of deriving the equation using Faraday's law for the hole is set as a variable value of the current flowing through the outer periphery of the hole, to construct simultaneous equations by causing formed continuously to these equations, the simultaneous equations and performs the step of calculating the electromagnetic field distribution of the metal structure surrounding using the current values ​​obtained and steps, determining the value of each current can be solved.
