my system is simple gas and is interacting under simple LJ potential. isn't there a simpler way to do a simulation for a constant energy mode?
i can remove pressure couling and temp. coupling. what kind of rigorous bond constraint algos do you mean? can you throw some more light on this topic?

thanking you,
karamyog.

Don't perturb the energy.... that is, don't use temperature or pressure
regulation and use rigorous bond constraint algorithms. Be aware that
use of cut-offs is inherently non-conservative of energy... watch the
total energy closely.
