Why are there no sharp current spikes in COMSOL official 1D DBD plasma argon example? How to obtain them?

Hi everyone,
I am studying the official COMSOL example of a 1D Dielectric Barrier Discharge(DBD) plasma argon discharge, and I noticed that the plotted terminal current waveform is relatively smooth and periodic.
In many DBD studies (both experiments and published simulations), the discharge current typically showssharp spike-like peaks(microdischarge pulses) superimposed on the displacement current background. However, in the COMSOL official 1D DBD argon example, the plotted terminal current appears to be a smooth periodic waveform without obvious sharp peaks.
I would like to ask two questions:
- Why are sharp current spikes not visible in the COMSOL official example?
- Which parameters/settings should be adjusted to observe sharp current spikes (if possible)?
Any explanation or suggestions would be greatly appreciated. Thank you!
