Did you try with ‘delete_atoms’ option? You can define group(s) near the surface of the spherical particle with specific roughness profile and detele atoms within these groups.

Dear All,

 

I am trying to create spherical particle (few tens of nanometers in size) with certain amount roughness . 

 

Can someone help me know whether its possible to incorporate roughness on a spherical particle using lammps commands?

 

 Otherwise, can anyone suggest other ways to do it in lammps. Thank you.
