I don't know if it's germane to your problem, but this is about the
tenth time this month that someone has reported an .mdp file with groups
of ions coupled independently to thermal baths. This is a Bad Idea, and
means that even if everything else is working correctly, your simulation
isn't as close to accurate as you would want. Search the mailing list
for reasons why.
