WebOct 17, 2024 · And I was looking for an in-built plotting function for the thermal displacements. In phonopy-API i found something regarding this but couldn't succeeded in plotting. However, now i could able parse the yaml file and write the two column file for plotting. But this is like going around. So i thought I could ask the forum.

WebPhonopy is an open source package for phonon calculations at harmonic and quasi-harmonic levels. as sources of inter-atomic forces and uses finite displacement method and symmetry relations for calculating elements of dynamical matrix. It works for all crystal symmetries and provides WebDec 1, 2024 · Phonopy code was used to obtain the phonon eigenvectors. Harmonic force constants were calculated by the finite displacement method using the 2 × 2 × 2 supercell of the conventional unit cell. We also employed Phonopy-qha to calculate the thermal expansion contribution to the frequency shift based on the quasi-harmonic approximation … WebThe following features of phonopy are highlighted: Phonon band structure, phonon DOS and partial-DOS.
