Dear Justin, Thanks for your respond, I assume there is a way to apply this restraint on specific molecules. Because my system is mixed with organic and water and I would like to apply these forces on organic molecules not water?
So apply flat-bottom restraints to whatever the organic molecules are. It's not something specific to ions. You set the restraints in the molecule's topology (in its [moleculetype]), construct a reference coordinate file that defines some unphysical coordinates to be used as the center of the restraint, and that's it. I've described the process in detail before so check the archive.
