JMAG-Designer provides not only the built-in material database, but also the function to create materials with arbitrarily defined properties(custom materials).
When creating a custom material, it is not necessary to set all parameters; only the parameters necessary for desired analysis can be set.
This script creates a custom material with the electric property parameters of an insulation material that can be used in electric field analysis.
Preconditions
- The units of the setting values follow the unit system set at [Tools]-[Preferences].
Script Function
- Create new custom material and set the electric property parameters.
Set the conductivity type to a constant value of 0 for electric conductivity, permittivity to a constant value of 2.4 for the real part and 0 for the imaginary part and 25000000 for dielectric strength.
