Hi Christoph,

I use the following .mdp gromacs script adjusted from the gromacs tutorial
to minimize the our CS system:

  1 ; minim.mdp - used as input into grompp to generate em.tpr

  2 ; Parameters describing what to do, when to stop and what to save

  3 integrator  = steep         ; Algorithm (steep = steepest descent
minimization)

  4 emtol       = 1000.0        ; Stop minimization when the maximum force
< 1000.0 kJ/mol/nm

  5 emstep      = 0.001          ; Minimization step size

  6 nsteps      = 100000         ; Maximum number of (minimization) steps
to perform

  7

  8 ; Parameters describing how to find the neighbors of each atom and how
to calculate the interactions

  9 nstlist         = 1        ; Frequency to update the neighbor list and
long range forces

 10 ns_type         = grid      ; Method to determine neighbor list
(simple, grid)

 11 coulombtype     = Reaction-Field      ; Treatment of long range
electrostatic interactions

 12 rcoulomb        = 1.0       ; Short-range electrostatic cut-off

 13 rvdw            = 1.0       ; Short-range Van der Waals cut-off

 14 pbc             = xyz       ; Periodic Boundary Conditions in all 3
dimensions


and I get the following error:


Steepest Descents converged to machine precision in 8003 steps,

but did not reach the requested Fmax < 1000.


Is this the right way to minimize the system? If so is there something
wrong with the initial configuration?

Thanks,
Mohsen
