WebJul 26, 2024 · Starting with an initial system, spglib is used to identify the associated primitive unit cell. The primitive cell is passed to phonopy, which constructs super cell systems with small atomic displacements. A LAMMPS calculation is performed on the displaced systems to evaluate the atomic forces on each atom without relaxing. WebJun 24, 2024 · Hi, 2x1x1 breaks the symmetry in a computational sense. I suggest 2x2x2. I mean % phonopy -c Sb3.POSCAR --symmetry -> number of symmetry operations = 48 % phonopy --dim 2 1 1 -d -c Sb3.POSCAR % phonopy -c SPOSCAR --symmetry -> number of symmetry operations = 32, but if properly found, it should be 48x2. So the symmetry is …
