Dear justin,
                  Thank you for your previous reply.
                  When i study the effect of ionic strength on stability
Which Parameter of Electrostatics Should i use? . If I use usual PME Then will it interfere it with result?. Because My system has Non zero charge I went through a Literature In that They used The "Cut-off" Coulomb Type But When I use the Same cut-off for my system It shows artifacts
warning
Thanks In advance


Mark already answered this earlier:

If your system has a non-zero charge I see no reason why you can't use counterions to balance the charge and increase the ionic strength to varying degrees from the neutral baseline.
