So instead of using epsilon-surface = 70, I should use its value equal to 1 ? By deault epsilon-surface = 0 which means it is turned off, to turn it on one must specify a value, as mentioned in Gromacs mdp options: "value of the relative permittivity of the imaginary surface around your infinite

Dear Justin I tried to run the simulation by changing cutoff scheme from verlet to group, but its giving error of too many LINCS warnings (1001), Any idea how to fix this issue I have already minimized and equiliberated my structure with nvt for few ps and npt for 5ns. Thanks On Mon, May 30,
