I am curious about the reason for the heating that allegedly occurs with cutoffs in NVE simulations ("The use of (electrostatic) cutoffs is well known to cause heating in NVE simulations."). This should not, and does not, happen if an appropriate smoothing function is applied. Does this heating mean that cutoffs are implemented in a sub-optimal fashion in GROMACS, or is it just a bug? Adding a heat bath would just hide the symptom, since there would still be an energy flow from the heat source, so simulations in other ensembles would also be affected?
