[lammps-users] How to remove thermostat?

Dear Lammps_users

     I equilibrate my system using Nose-Hoover thermostat (NVT ensemble).
     I want to do next operation with adiabatic condition.
     So I need to remove the thermostat.
     How to do it within a NVT fix?
      Does someone have the experience for this?
      Thanks in advance!

Best Regards

after your equilibration you should unfix the NVT fix and put an NVE (or another) fix at its place. It looks roughly like this in the Input script:
fix 1 all nvt …
run …
unfix 1
fix 2 all nve
run …
