Hi Galaa, I’ve seen similar things, large isolated, unphysical excursions in otherwise perfectly reasonable results when plotting data from a meep output. Are you using Matplotlib/pyplot for your plotting routines? And do the excursions appear at exactly the same points and with the same amplitudes reproducibly or do they vary unpredictably? I would be quite interested to know if anyone has a good explanation and a good fix.
