Steve,
Sorry I mailed to your inbox, better I am mailing again in the mail list.Steve,
In my model, I want to select any atom of my interest from my
simulation box and then impart it a certain velocity in a particular
direction. I can use velocity set command with vx,vy,vz co-ordinate
for imparting velocity to that particular atom.
Now, I have a question regarding how do I select a particular atom. As
velocity only accepts group ID, do I have to define a group
containing single atom. Or is there any other command in LAMMPS to do
so.
I have seen set type command for selecting an atom of any ID , for eg.
I can use
set atom 1500 type 1,
but how do I relate this to group ID.
Thanks,
Agraj Abhishek
