Steady state AC Electric 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 |
air or a vacuum (permittivity εr =1) |
(predefined) |
| perfect conductor |
of a perfect conductor medium: equipotential frontier (floating or fixed value of electric potential) with a normal electric field |
an imposed electric potential: floating or fixed value (in V) |
| dielectric and non-conducting |
of a dielectric non-conducting medium (εr permittivity) without dielectric losses |
a material with : real εr permittivity |
| dielectric and conducting | of a dielectric, conducting or not, with or without dielectric losses(complex εr permittivity and/or ρ resistivity), |
a material with : complex εr permittivity ρ resistivity |
