WebPhonopy has an interface to read and write FORCE_CONSTANTS or force_constants.hdf5. To read and write these files are controlled by force constants tags and FC_FORMAT, … WebAug 21, 2024 · Phonopy is then run a second time to parse these forces and generate a so-called force set out of it The third time Phonopy is called, it is used to actually calculate and generate a plot of the phonon band structure for a given path Phonon band structure for … farim phosphate
