Contents I. Introduction
Numerical simulation plays a crucial role in the design and control of electrical devices. The finite element (FE) method is a widely utilized numerical approach to solve partial differential equations (PDE) that model physical phenomena and therefore exhibits high accuracy in reflecting real-world scenarios. However, this method creates a system of equations with a high number of degrees of freedom (DoFs), resulting in a significant computational burden. As a result, utilizing FE models for complex applications, particularly in multi-physics simulations, can be difficult. To enhance computational efficiency, several model order reduction (MOR) techniques have been implemented [1].
