Steady State AC Magnetic volume (3D) / face (2D) region

Introduction

The volume (in 3D) / face (in 2D) regions are the material regions used to model the massive regions in the study domain.

Material regions (massive regions)

Material massive regions enable the modeling of the material media (with materials). The physical properties of the medium are those of the corresponding material region.
