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?
It doesn't get any more simple than "don't do anything"! In gromacs,
something approximating NVE is the result of doing nothing. Determining
how large any cutoffs are is the next step in the quality of the
approximation to true NVE.
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?
It sounds like you don't have any bonds - if you search for NVE in the
manual you will hit a comment in about lincs_iter that might be
relevant, I can't comment.
