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 … WebNov 19, 2024 · phonopy -f {001..010}/vasprun.xml This command is run from the directory that holds the 001 through 010 directories.
