ElectricCurrentDensity¶

Type:	1-Tensor, or section
Range:	[v_1, …, v_3]
Default:	-/-
Appearance:	optional

Specifies an electric current density $\VField{J}$ in units amperes per square meter, $\units{A/m^2}$ .

Note

A ElectricCurrentDensity is only definable for a physical domain. So, setting BoundaryId in the parent section is not allowed.

A constant electric current density can be defined by assigning a 3-vector:

# define a constant electric current density
ElectricCurrentDensity = [..., ... , ...]

For more general cases, an electric current density may be given as a section in order to deal with space, time, and parameter dependent definitions:

# define an electric current density as a section
ElectricCurrentDensity {
  Constant {...}
  Python {...}
  LineSource {...}
  PointSource {...}
  ...
}

Field definitions within this section are summed up. Consult the subsequent sections to see which types of field definitions are allowed.
