Hello!
Should I use rlist larger than rcoulomb also for PME calculations? Somehow I was
understood that rlist should be equal to rcoulomb in that case but atleast I
can't achieve energy conservation otherwise than using rlist>rcoulomb(&rvdw).
Of course I get equal results for energy conservation if I use nstlist=1.
If I remember right there has been problems in earlier versions so that rlist
couldn't be larger than rcoulomb but atleast now it is possible. However rlist
still can't be larger than rvdw for single-range cut-off and I was wondering if
there is some specific reason for that?
Thanks for any comments!
