External Temperature (Thin Layer, Thin Film, Fracture)
Use this subnode to specify the temperature on the exterior side of a thin layer, a thin film, or a fracture, when Layer type is set to Thermally thick approximation or General, on exterior boundaries.
Temperature
For User defined, enter a value or expression for the Temperature T0. Else, select an Ambient temperature defined in an Ambient Properties node under Definitions.
The equation for this condition is T = T0 where T0 is the external temperature to be prescribed.

You can specify a harmonic variation of the temperature value in a frequency domain analysis of perturbation type, by adding a Harmonic Perturbation subnode. See Theory for Harmonic Heat Transfer for more details.
