Hi Jio,

There is no requirement for the total energy, or the potential energy to be
negative. The energy origin is actually somewhat arbitrary in molecular
dynamics simulations so individual energy values do not tell you much, you
need to look at relative energy differences, magnitudes of fluctuations etc.
All the best
