Time Derivation Settings ?

Hello,

I'm having a "problem" with the time derivation of a Psi curve. The derivation itself works, BUT it doesn't look as nice as I want it to.

I attached the Psi-curve (with respect to time), the negative timely derivation (e-curve) and a comparison between the curve I get with COMSOL and the curve I want it to look like (ignore the time offset please).

Are there any settings for the time derivation in COMSOL? I use the following command in a time dependent research within the electrical machines interface:

-d(Psi,TIME)

Or is there maybe a way to smooth the Psi curve a bit, since there are very many little changings in a small frame of time?


Thanks in advance
