A full-wave electromagnetic field equation in a cross section of a ferrite core, modeled as an array of grains, is solved with the finite element method utilizing local model order reduction techniques. With the traditional finite element method and a high number of grains, the resulting system becomes resource-intensive. The reduced approach greatly decreases the amount of degrees of freedom and the computational time for solving the resulting system.
