ThermalConductivity

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

Defines the thermal conductivity k. Units are Watt per meter kelvin, \units{W/(m K)}.

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

Material {
  # defines a constant thermal conductivity
  ThermalConductivity =
      [..., ..., ...
       ..., ..., ...
       ..., ..., ...]
}

Assign a scalar for an isotropic thermal conductivity .

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

# define the thermal conductivity  as a section
ThermalConductivity {
  Python {...}
  ...
}

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