WebDec 2, 2024 · Phonopy can give you the eigenvectors of the modes. In conjunction with the 'q' shifts (displacements for the supercells, generated by phonopy), this can tell you the nature of the mode. For example, if the eigenvector points in the same direction as the 'q' shift, it is a longitudinal mode. 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 …
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). Disclaimer: I am an author of the nondiagonal supercell … WebPhonopy is a free, open-source software for calculating phonons via harmonic and quasi-harmonic approximations, utilizing the direct force-constant method.
