Dear All,

I want to calculate the PMF (Potential men force) in my system. I am doing Non-equilibrium MD simulation of water/ion transport through CNTs. I am wondering about PMF calculation using Pair distribution function (PDF) or Radial distribution function (RDF) by means of these eqs.

w(L) = - k_BT * log(g(L))  (using PDF along the length)

w(r) = - k_BT * log(g(r))  (using RDF alond the radius )

Can I make use of those methods to do PMF calculation in Non-equilibrium simulations?

Thanks in advance
