This
dialog offers the possibility to define the dependencies of thermal conductivity
and specific heat capacity on temperature. In the following plots, approximate
curves for copper are shown, allowing to simulate the melting process
in the transient thermal solver:
Temperature
values must be specified in the currently selected units. Thermal conductivity
and heat capacity values must always be positive. Beyond the specified
temperature intervals, the corresponding material parameters are assumed
to be constant.
Material parameter:
Selects the nonlinear material parameter being
specified. It is possible to choose between Thermal
conductivity and Heat capacity.
The latter choice leads to an error message, if zero default value has
been specified in the Material
Parameters dialog.
OK
Accepts the input and closes the dialog. Please
note that at least three data points must be defined for correct interpolation.
Preview
Displays a preview of user-defined and fitted curves
for all the components of nonlinear thermal conductivity.
Cancel
Closes this dialog box without performing any further
action.
