Erik, Do you mean that if the particle diffuses too fast, it will appear like it doesn't move because of the PBC?
I have another issue. If I have a polymer chain with the length almost the same as the box length. It is possible that the COM diffusion of the chain may appear it does not move or move backward due to PBC, right? Thank you so much!
