    • To create a frequency-independent metal, from the Definition method drop-down list select Frequency independent.
    • To create a frequency-dependent metal, from the Definition method drop-down list select Frequency list (linear interpolation).
      • To enter each frequency point manually, enter the magnetic properties for each frequency point.
      • To import the frequency points from a file, click Import points.
        1. In the Filename field, browse for the file you want to import.
        2. [Optional] In the Scale by field, enter a value to scale the points.
