hello amber users,
I am new user. When I tried to minimize one structure, I got following
message.

NSTEP ENERGY RMS GMAX NAME NUMBER
  10000 -8.6148E+07 5.1600E+11 5.2770E+13 H2 10140

 BOND = 955.1086 ANGLE = 1159.3031 DIHED =
4954.8413
 VDWAALS = -2911.0127 EEL = ************* HBOND =
0.0000
 1-4 VDW = 1788.4797 1-4 EEL = 19090.7988 RESTRAINT =
0.6814
 EAMBER = *************
 Frac coord min, max: -8439365.76177023 8439367.24932251
 The system has extended beyond
     the extent of the virtual box.
 Restarting sander will recalculate
    a new virtual box with 30 Angstroms
    extra on each side, if there is a
    restart file for this configuration.
 SANDER BOMB in subroutine Routine: map_coords (ew_force.f)
 Atom out of bounds. If a restart has been written,
 restarting should resolve the error
"min.out" 1045L, 47424C

The input file was this -

title
&cntrl
 imin=1,ntmin=1,
 maxcyc=20500, ncyc=10000,
 ntpr=1
 scee=1.2, scnb=2.0,
 nsnb=999999,
 ntb=0,
 cut=12,
 fcap=1,
&end


Could you please tell me what it means ?

Regards,
k
