摘要：

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 (FE) method utilizing local model order reduction (LMOR) techniques. With the traditional FE method and a high number of grains, the resulting system becomes resource-intensive. The reduced approach greatly decreases the amount of degrees of freedom (DOFs) and the computational time for solving the resulting system.
