[lammps-users] question on mementum command

dear all,

If I perform NVT simulation without momentum command, it succeed to end normally.
However, if I use momentum elimiantion at every step by adding “fix 1 all momentum 1 linear 1 1 1 angular” between “initial velocity assignment command” and “fix temp/berendsen and fix nve”, it stop during the simulation (it stops at the same step).
What’s wrong with it and what should I do for it?

Best regards,


I wouldn't use fix momentum with a thermostat. They may work
at cross-purposes, as both adjust atom velocities. Did LAMMPS just
stop without an error message or crashing? That seems somewhat
