Thank you very much, Berk! 1) That only leaves one unanswered point, that seems logical but of which I would like to be certain of.. Is there any accessible term in the reaction field implementation accounting for long-range electrostatic interaction due to the environnement dielectric? Or is this contribution simply added to Coul-SR?
2) Last, I have a situation that I cannot understand, comparing RF and PME for a 100 residue protein in a water cubic box of roughly 70*70*70A. Comparing contributions of energy groups (g_energy), I obtain: -Reaction field: |coul-SR prot-prot| > |coul-SR prot-other| -PME: |coul-SR prot-prot| < |coul-SR prot-other| (the opposite) (with "||" for absolute values) Would that be because of the long-range electrostatic contribution (with the environnement dielectric), added to coul-SR as I suggest in 1)? Thank you very much for your help!
