I am doing an energy minimization in a vacuum condition. There is no "emtol" in the mdp file. The energy converges in the end, and tell me "Fmax < 10" as shown below. So how this "< 10" is determined?
Steepest Descents converged to Fmax < 10 in 4063 steps Potential Energy = -2.3973977e+04 Maximum force = 9.8130465e+00 on atom 405 Norm of force = 1.5696382e+00 My mdp file is: integrator = steep nsteps = 10000 nstxout = 0 nstfout = 0 nstlog = 100 cutoff-scheme = Verlet nstlist = 20 ns_type = grid pbc = xyz verlet-buffer-tolerance = 0.005 coulombtype = reaction-field rcoulomb = 1.1 epsilon_r = 15 ; 2.5 (with polarizable water) epsilon_rf = 0 vdw_type = cutoff vdw-modifier = Potential-shift-verlet rvdw = 1.1 -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
