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
T
0
. Else, select an
Ambient temperature
defined in an
Ambient Properties
node under
Definitions
.
The equation for this condition is
T
=
T
0
where
T
0
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.
