ElectricConductivity¶

Type:	2-Tensor, or section
Range:	[v_1, …, v_9]
Default:	-/-
Appearance:	optional

Specifies the electric conductivity $\TField{\sigma}$ . Units are siemens per meter, $\units{S/m=1\Omega^{-1}m^{-1}}.$

A constant electric conductivity can be defined by assigning a rank-2 tensor:

Material {
  # defines a constant electric conductivity
  ElectricConductivity =
      [..., ..., ...
       ..., ..., ...
       ..., ..., ...]
}

Assign a scalar for an isotropic electric conductivity.

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

# defines the electric conductivity in a section
ElectricConductivity {
  Python {...}
  ...
}

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