Create_atoms command

WebThis command creates atoms (or molecules) on a lattice, or a single atom (or molecule), or a random collection of atoms (or molecules), as an alternative to reading in their coordinates explicitly via a read_data or read_restart command. A simulation box must already exist, which is typically created via the create_box command. WebCreate atoms on a lattice using lattice, region, create_box, create_atoms. Atoms cab be defined also froam a data or restart file. ... so in one of the directions we will have \(\sqrt{1225}=35\) atoms separated one cell unit.
