But would there be a way to optimize it further? In my real simulation i would have a charged solute and the uncharged solvent (both have nearly the same number of particles). If i could omit the uncharged solvent from the long-ranged coulomb-calculation (PME) it would save much time. Or is the

Dear all, Is there a way to omit particles with zero charge from calculations for Coulomb-interactions or PME? In my calculations i want to coarse-grain my solvent, but the solute should be still represented by atoms. In doing so the solvent-molecules have a zero charge. I noticed that for a si
