[Users] weird waveform for binary black holes system

Hi all,

I am using Einstein toolkit to simulate binary black hole merger, and I was trying to repeat https://einsteintoolkit.org/gallery/bbh/index.html. But I end up with a weird waveform like(I did not finish all the simulation, but it has started to look weird of the peak around t=300) [image: image.png] rather than(the right one )

[image: image.png] I am planning to run it again for a longer time, it would be really helpful if anyone knows what's wrong with my last running so that I can edit it before redoing it. Thank you for your time.
