Electro Static line (3D) / point (2D) region
Introduction
The line (in 3D) / point (in 2D) regions are:
-
either material regions: used to model filiform regions in the study domain
-
or non-material regions: used to impose boundary conditions (BC) inside or on the frontiers of the study domain
Material regions (filiform regions)
Filiform regions enable the modeling of regions of small cross-section.
The filiform regions are described in the same way as the massive regions, with in addition the cross-section of the region.
In 3D, the direction of the electric field is imposed by Flux. The electric field is usually considered tangent to the line that models the filiform region.
Non-material regions
Non-material regions enable to impose the boundary conditions (BC).
| A region… | is a BC that enables one to impose… | It is defined by… |
|---|---|---|
| Perfect conductor | an uniform electric potential and a normal electric field |
an electric potential: floating or fixed value (in V) |
| Imposed linear charge | a linear density of electric charge |
a linear density of electric charge (in C/m) (formula with input/output parameters or formula with spatial quantities) |
| Imposed electric potential | an electric potential |
an electric potential (in V) (formula with input/output parameters or formula with spatial quantities) |
