Electric Transient Excitations
The following excitations are available for electric transient problems:
- Charge – This excitation can be applied to 2D surfaces or 3D volume bodies, if a body has net charge q. This type of excitation defines the total charge on a surface or object.
-
Current – This excitation can be applied only to 2D surfaces, where the total current flowing in/out of that surface is specified.
-
Floating – This excitation can be applied to 2D surfaces or 3D volume bodies; then these 2D or 3D objects are with equi-potential. This type of excitation models conductors at unknown potentials and specifies the total charge on the conductor.
-
Sink – This excitation can be applied only to 2D surfaces that are grounded with reference potential value. It is the same as applying zero voltage excitation on those surfaces.
-
Voltage – This excitation specifies the value of the electric scalar potential value on 2D surfaces or 3D volume bodies.
-
Volume Charge Density – This excitation can be applied only to 3D volume bodies. If the body has net charge q, the charge density is q/VOL, where VOL stand for the volume of that body.
