When understanding complicated phenomena, it is sometimes useful to check analysis results by focusing on specific frequency components. JMAG can convert the distribution obtained by transient analysis to the frequency domain.
This document shows how to display output results ij vector form using the Fourier transform calculation function.

Table.a Distribution Analysis Function
|Fourier transform calculation||・Converts time domain results to frequency domain.
・Used when evaluating the distribution at a specific frequency.
|Frequency filter calculation||・Extract only specified frequency components from the time domain and convert them back to the time domain.
・ Used when evaluating of the distribution at each time step for a given frequency and position on a part.
