Law of calculation of harmonic calacul frequency

Hello

I am trying to know the law of calculation of calculation frequencies during harmonic calculation under simulation (dynamic analysis).

When you choose linear, it's quite simple (equal division of the range between two characteristic frequencies by the number of frequency points weighted by the grouping ratio).

But when you choose Logarithmic, I can't find the law. The help simply says "The simulation frequency points are grouped logarithmically for each natural frequency". It's a bit vague.

Anyone have an idea?

Thank you
