My objective is to use Poisson equation based mean field approximation for
the electrostatic interactions. So, I need to figure out how to achieve
this in Gromacs.
I understand PME uses Poisson equation for the long-range component in
addition to the direct Coulomb sum for the pairs within a specified cut-off
So, to keep only Poisson part of the electrostatic, I should set
short-range Coulomb sum to be zero. This can be achieved, as I understand,
by using "pme-user" setting for the Coulomb and setting 2 and 3 coulumns in
the table.xvg to zero.
I would appreciate if someone could verify that the above approach is
correct way to approximate Poisson mean field approximation for
