This node defines the thermal conductivity and thermodynamics properties of a resistive material located on internal or external boundaries. This material can be formed of one or more layers.
Select the applicable layers (the default setting is All layered materials) defining the required material properties for the node.
When a layered material stack or link is selected from the Layered Material list, clear the check boxes corresponding to layers where the node should not be applied in the
Selection table.
This section is available when a temperature-dependent density defined in a material is used. On the material frame, the density is evaluated onto a reference temperature to ensure mass conservation in the presence of temperature variations. By default the Common model input is used. This corresponds to the variable
minput.Tempref, which is set by default to 293.15 K. To edit it, click the
Go to Source button (
), and in the
Default Model Inputs node under
Global Definitions, set a value for the
Volume reference temperature in the
Expression for remaining selection section.
The other options are User defined and all temperature variables from the physics interfaces included in the model.
This section is available when temperature-dependent material properties are used. 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 default Thermal conductivity k is taken
From layered material. For
User defined select
Isotropic,
Diagonal,
Symmetric, or
Full to enter another value or expression.
By default the Density ρ and
Heat capacity at constant pressure Cp of the layer are taken
From layered material. For
User defined enter other values or expressions. These properties are only used in time-dependent studies, but must be set in all cases.
