Select the boundaries on which to specify the thermal contact. If a layered material (Material with
Layer thickness specified,
Single Layer Material,
Layered Material Link, or
Layered Material Stack) is available, its name is then displayed beside the boundary index (for example,
slmat1), otherwise the boundary is marked as not applicable.
The available options in the Apply to list are
Interior interfaces and
Selected interfaces. With the second option you can select any set of internal interfaces for a given layered material, by clearing the check boxes corresponding to layer interfaces where the node should not be applied in the
Selection table. See
Interface Selections for more details on the interfaces identification.
This section is available when material properties are temperature-dependent. By default, the temperature of the parent interface is used and the section is not editable. To edit the Temperature field, click
Make All Model Inputs Editable (
). The available options are
User defined (default),
Common model input (the
minput.T variable, set to 293.15 K by default) and all temperature variables from the physics interfaces included in the model. To edit the
minput.T variable, click the
Go to Source button (
), and in the
Default Model Inputs node under
Global Definitions, set a value for the
Temperature in the
Expression for remaining selection section.
The available options to specify the resistive behavior of the gap are Gap resistance (default),
Gap conductance, and
Gap thermal conductivity and thickness. Depending on the selected option, enter values or expressions for the
Gap resistance,
Req, the
Gap conductance,
heq, the
Gap thermal conductivity,
keq, and the
Gap thickness,
ds.
By default the Surface emissivity, upside and the
Surface emissivity, downside,
εu and
εd, are taken
From material. For
User defined enter another value or expression.
