limiting the velocity in one direction

Dear users,
Is there any way to limit the moving velocity of a group of atoms in one direction, say z?
As I could find in the manuscript, “nve/limit” could be used for limiting the displacement in each timestep, but not in a specific direction. Also, “move” is for a predefined movement.
Any help would be appreciated,


Setting realistic model parameters :slight_smile:

Really, do you think you need to apply artificial constraints to the system?

You can use fix lineforce or fix planeforce to

have atoms move only in a constrained space.
