Carbon velocity upon deposition in copper surface

Hello lammps-users

How can I compute the value of the velocity for the deposition of carbon on copper surface? I am assuming there is a certain equation to compute for the vz. Currently, I am using the sample value from lammps manual like “vz -1.0 -1.0” . Thank you very much!

​no, there isn't. you set the velocity to a range that matches the kind of
experiment you want to model and thus matches the incident velocity​ you
would need.
