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:

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:
