I have one question regarding an example (under folder of bench, in.chain, data.chain, log.9Jan09.chain.fixed.linux.1).
In this simulation, “NVE”+“langevin” are employed, which perform a brownian dynamics.
In the log file, we can see that the temperature and total energy are stable (I ran longer timesteps, they are stable).
My question is that: The total energy is positive, is this system stable or not?
Generally speaking, negative total energy is better for a stable system.
p.s. the files of this example are attached.
Thanks & Best wishes,
