Calculation of the magnetic field of scattering taking into account ferromagnetic elements by the method of finite differences.

Abstract

Based on the finite difference method, an algorithm was developed for the Minsk-32 computer in the FORTRAN algorithmic language, a program was developed for calculating the magnetic field of a transformer scattering taking into account ferromagnetic elements located inside the region (pressing rings, magnetic shunts, etc.). The problem was solved in linear formulation. The program allows for an arbitrary ratio of the sides of a rectangular area to set the number of grid nodes to 720. The print displays the values ??of the vector potential and induction at the grid nodes, as well as graphs of lines of force magnetic field. The program has an average operating time of 200 s.
