MD simulations using Forceit

Dear all,

I have been following a tutorial on Forceit plus. I did the tutorial 3 times, using the same parameters. However, each time the simulation is run, the values obtained in the study table for hamiltonian energy as well as all the other energies is different. The are still quite similar, but not exactly the same. Why is this?

Also when I calculate binding energy, would I use Hamiltonian energy or the total potential energy?


Kind regards
