Why do you think this is a problem? This isn't exactly a crystal or a
fluid... Besides, you know everything about the system down to the LJ
parameters. Why not do an analytical estimate?

I simulated the mixture of argon and krypton(400 atoms).After equilibration
run with NPT ensemble at temperature 300k and pressure 1 bar with
compressibility 1 bar-1, I obtained required density and pressure but the
potential energy was negative and total energy was positive.Is it (positive
total energy ) matters or not?
