system energy

Please address to the mailing list, not individuals, for general
LAMMPS questions. However, your questions are conceptual ones, not
LAMMPS ones.

Hello Ray,
I have some questions, hoping you can answer. I know at different
temperatures, the system energy is different. So, does temperature affect
the adhesion energy?

Sure, why not?

And, i found that if I changed the box size in data
file, the force of atoms changed a lot but the energy is almost same. I set

There is not enough information on how box size was changed. Created
vacuum space? Still bulk and periodic? Atoms remapped? etc.
