If you have "unprotected" electrostatic sites (i.e. with nonzero repulsive terms directly on top of the charge), then there will always be some configurations with essentially infinitely negative energy. For vanilla MD, these are essentially impossible to reach kinetically at any reasonable temper

Hi all, I have a rather strange question that I hope someone can shed some light on. Before I begin, I want to note that I am pioneering some new developments of the Adaptive Resolution Simulation technique (https://doi.org/10.1002/adts.201900014), so the simulations/techniques I am performing/im
