empty dump and restart files

Hi all,

The issue I have run into is that after about 30 ps of the run, the generated dump and restart files are empty. However, the system seems to be stable, as the run is not terminated, no big energy fluctuations are observed and the specified data is properly recorded in the thermo file. I’m wondering what could be the cause of this problem.
I’d truly appreciate your response.

Best Regards,

Hi Ray,
Thanks for your response. The input script is as follows:

** Initialization **

bond_style harmonic
angle_style harmonic
dihedral_style opls
pair_style lj/cut/coul/long 8.5
kspace_style ewald 1.0e-4
pair_modify mix arithmetic

** Atom Definition **

read_restart Restart.33000

** Setting **
