Transient 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.

A massive region … enables the modeling … It is defined by …
air or vacuum of the air or of the vacuum

(predefined) (permeability μr = 1)

magnetic non conducting

of a medium: magnetic non-conducting

a material with: permeability μr

solid conductor

of a medium: magnetic conducting

a material with: permeability μr

resistivity ρ

coil conductor

of a medium: conducting with source

non-magnetic

→ this medium represents a coil:

  • constituted of a number of turns
  • passed through by current

a number of turns an electric component

laminated magnetic non conducting

of a laminated medium: magnetic (permeability μr) non conducting

→ this medium represents a stacked magnetic sheets:

  • plane (2D plane / 3D) or cylindrical (3D)
  • simplified via a homogenization technique
a material with: permeability μr a thickness of sheet iron a stacking factor

Specific to 2D and 3D with current density

of a medium: conducting with source non-magnetic
