Hi, I don't think so, because it's trivial - it's defined as the value of the potential at the distance of the cutoff. Mark On Thu, 10 Aug 2017 19:44 Natalie Paige Schieber < natalie.schie...@colorado.edu> wrote: > Hi all, > > I am using the potential-shift-verlet keyword for the

[gmx-users] Potential Shift Verlet

2017-08-10 Thread Natalie Paige Schieber
Hi all, I am using the potential-shift-verlet keyword for the coulomb-modifier. I am attempting to find the specific equation for this treatment of the electrostatics. In the manual for the most recent version of Gromacs I found an equation for potential-switch (eq 4.30) but not shift. Is there

Hi, It's often nice as a user to know that the program has agreed with your intentions :-) You're using a tabulated interaction, so AFAICR mdrun just does what you say. In some cases, mdrun will generate tables to implement the user's short-ranged options, and it's important that mdrun says what

Dear GMX users, Does anybody know why the "Potential shift: LJ r^-12: 0.000e+00 r^-6: 0.000e+00" is written in my case.log file in spite of using LJ(6-9) in my calculations? Table routines are used for coulomb: TRUE Table routines are used for vdw: TRUE Cut-off's: NS: 1 Coulomb: 1.26
