[lammps-users] Add velocity.

Hi Lammps Manager,

I have a question on Lammps --

Can it add a translational velocity (e.g., add vx=1.00) into the model during the whole simulation??? This adding velocity could be added at each time step, or just at initio step.

Best regards,


You can set/add a velocity at the beginning via the velocity
command. You can add a force at any timestep via the
fix addforce command, which effectively adds dt*f velocity.
If that's not what you want, you could write a fix addvelocity
