DC Conduction Boundaries and Excitations
The following excitations can be specified as the source of electric fields:
- The voltage difference between surfaces and objects. Define the electric potential on each surface and object using a voltage excitation.
- Using the current excitation, define the total current flowing through a surface or a 2D object.
- Using the sink excitation, define a collection of surfaces or 2D objects as a sink. Sink excitations are applied when only current excitations are defined in a conduction path and there is no voltage excitation. In fact, in this case, a sink excitation has to be defined and it ensures that the total current flowing through the outside surface of a conduction path is exactly zero.
Include at least one of the following as a reference for computing the electric potential:
- A voltage excitation.
- A sink excitation.
- An odd symmetry (flux normal) boundary.
