[gmx-users] virtual site, dummy massive site

[Faezeh Pousaneh]

I have 2 questions please. They seem evident, but I need to be sure to
solve my simulation problem:

1- Does being a virtual site (charge, no mass) or a normal atom, effects on
its LJ interaction energies with rest of system?

2-  Does adding a dummy massive site (no charge, only mass) to atoms of
mono-atomic system, influences on the LJ energy of whole system?

Best regards
