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.

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.
