Dear Lammps users,
I ran my new simulation using a restart file from my old simulation with contains fix move command to move a group of particles in one direction.
Now in the simulation running now, without including the same fix move command, in the dump file it is giving the same velocity component . I visualized it and there it is not moving.
I exclude the same group from nve integration in the second simulation .
I want to calculate the force on that region . I afraid that the non-zero velocity component in the dumped file affect the calculation of the same.
- if you don’t specify fix move in the 2nd input script,
it won’t be active after the restart. See the fix move doc page
-
If you don’t time integrate particle, they won’t move.
-
What pair style are you using. Almost no pair styles depend
on velocities to compute forces. Granular and dpd are exceptions. -
If you don’t want certain particles to have a velocity, you
can zero them with the set command.
