Temperature Dependent Materials

In this dialog, the dependency of the relative permittivity  , relative
permeability  and electric conductivity  on temperature can be defined. For example,
an approximate temperature dependency of electric conductivity of copper
is depicted in the following plot:
Besides, the specific temperature field can be selected to be used with
this material. Temperature dependent materials are currently supported
by HF
Time Domain Solver and Stationary
Current Solver. Please note that the former solver currently supports only temperature distributions
defined on the hexahedral mesh, whereas the latter can handle both tetrahedral and hexahedral based
distributions.
Temperature field
In this combobox, the temperature distribution
to be used with the current material can be selected. The following possibilities
are provided:
Automatic:
select this item in order to utilize the default temperature distribution
(e.g. the first in the list of imported fields).
Import field...:
import a
new temperature distribution and use it with the current material.
Otherwise, select an already imported temperature
field.
Temperature dependency
In this group, the dependencies of the relative
permittivity , relative permeability and electric conductivity on temperature
can be defined. Select the specific parameter in the Parameter
combobox and define the corresponding dependency curve. If the temperature
dependency for any parameter is not defined, the default constant value
is utilized.
Delete
Deletes the currently selected item from the list.
Delete All
Deletes all items in the list.
Import...
Imports the data from a text file.
Export...
Exports the data into a text file.
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 the temperature dependency of the selected parameter.
Cancel
Closes this dialog box without performing any further
action.
