Hi LAMMPS users,
I am new to LAMMPS and I am seeking some help to create my super cell, I am confused about when can I use codes like packmol to create me cell by replication and when can I use the "lattice command".
I am creating a zircon cell with body center tetragonal crystal structure. I used packmol to replicate the coordinates but I found a note in one of the questions in the mailing list stating that packmol is a powerful tool but creates only coordinates and we need to use another code to create the molecular topology.
I know that it is a primary question but i am in a very bad need to direct me some clues or just direct me how to search about this.
Thanks in advance.
