What Formulation Should One Choose for Modeling a 3D HTS Magnet Motor Pole with a Ferromagnetic Material?

Abstract

We discuss the relevance of several finite-element formulations for systems containing high-temperature superconductors (HTS) and ferromagnetic materials (FM) in the context of a 3D motor pole model, in terms of their numerical robustness and efficiency. We propose a coupled h-φ-a-formulation as an optimal choice, modeling the problem with an a-formulation in the FM, and an h-φ-formulation in the remaining domain.
