WebPerform a phonon calculation#. Setting up a phonopy calculation is similar to settings up a relaxation (or any other workflow supported by FHI-vibes).To ensure that our physical settings don't change, we will copy the relaxation.in obtained in the previous part of the tutorial to the new working directory and rename it to phonopy.in.Please delete the … WebJan 13, 2024 · The phonopy and phono3py codes are widely used open source phonon calculation codes.

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 … WebSynonyms for PHONY: fake, counterfeit, forged, false, bogus, synthetic, sham, manufactured; Antonyms of PHONY: real, genuine, authentic, bona fide, actual, natural ... WebJul 8, 2024 · Using Phonopy this would be completely impossible, as it would require a supercell of size 110,592 (containing 221,184 atoms)! This calculation is in fact possible (and relatively easy), using nondiagonal supercells, which would only require a supercell of size 48 (containing 96 atoms).
