Hey Giorgio, thanks for the reply. I noticed that I didn't disable anti-aliasing during the warmup period. So it was enabled from the beginning. I'm not sure if that is the reason for the time step error, but I'm currently trying to run it again with anti-aliasing enabled at t=100, when I switched to p=4 and see if it makes any difference.
