I´m performing a simulation of an ion in water (TIP3P) using reaction
field. I define energy_grps = ion sol in my .mdp file.
When I use rlist = rcoulomb, no LR terms appear in g_energy list.
When I use rlist < rcoulomb, these LR terms appear.
So, the LR terms obtained using reaction field is the contribution of
implicit solvent between rlist and rcoulomb or the contribution of
implicit solvent beyond rcloumb, as is said in GMX manual and other
reference texts?
Thanks
No, the LR energy is still the directly computed energy between the R*.
The reaction field effect is implicit in the Coulomb potential, except
when you have larger molecules and an exclusion correction term is added.
