Hi my friends!
I am using LAMMPS to simulate an eam system recently. I want to use velocity command for applying pure shear.My velocity value is (0.0006 Angstroms/picosecond).I don’t know which command is true…
Command number 1 or 2 ???

  1. velocity middle ramp vx 0.0 0.0006 y {lim02} {lim03} sum yes
    or
  2. velocity middle ramp vx 0.0006 0.0006 y {lim02} {lim03} sum no

May anyone give some advice to make the system on the true way ?
Thank you in advance.

regards,
Nili

why don't you try both and see which one gives you the result you
desire, if any?
that is easy enough to do and the "scientific way" to solve a problem.
