Dear Gromacs user,
I am calculation the PMF of a single water molecule to pull it away from
top of metallic surface along vacuum in the Z direction ,following the
Justin umbrella tutorial. I am only interested in the behavior of PMF in
0.002 nm to 0.8 nm intervalon top of the surface, but I do not why the
population of the generated frames in this interval is really low and then
the result is so poor.
So, would you please let me know which parameter I should play around with?
I just tried 0.001 instead 0.01 as the "pull_coord1_rate" and simultaneously
3500 instead of 1000 as "pull_coord1_k", but the result got even worse.
Best regards,
Alex
