[lammps-users] Initialization using SW potential

Hello,

   I am preparing an input file for NVT simulation using SW potential.

1. How to do random initialization. As of now I am initializing by hand
and using read_data. Since I need to partition my system (defining
different regions) I have to define a lattice. I don't know how to have
random initialization with lattice defined.

2. I am not able to use reduced units for SW. But real units is working fine.

Regards
Aparna

Initialize what?

Initialize what?

initialization of particles for a choosen density.

Use the create_atoms or read_data command. The
former puts them on a lattice, but if you heat them
and run dynamics, they'll become amorphous if that's
what you want.
