Sorry, I am pasting the files now...
This is the case for 1ns 300K vacuum MD for a protein
This is MDin file:
1ns vacuum MD
&cntrl
imin = 0, ntb = 0,
ntpr = 5000, ntwx = 1000, ntwr = 1000,
ntt = 1, ntp = 0,
tempi = 0.0, temp0 = 300.0,
nstlim = 1000000,
cut = 10.0
&end
and I get the following output message just at the instant of 0 ps of MD:
Frac coord min, max: -3.26662690012118D-004 0.826317897389839
[12] MPI Abort by user Aborting program !
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.
EWALD BOMB in subroutine Routine: map_coords (ew_force.f)
Atom out of bounds. If a restart has been written,
restarting should resolve the error
[2] MPI Abort by user Aborting program !
[2] Aborting program!
Actually, I do not understand why this happens at 300K ?
Thanks.
