WebFirst, you need to create a phonopy input file with, e.g., ANIME = 0.5 0.5 0 . After running phonopy with this input file, you get anime.ascii that contains all phonon modes at the q -point. Then start v_sim. After opening the graphical user interface, you can find a tab … Webfc2.hdf5 and fc3.hdf5 are created from FORCES_FC3 (and optionally FORCES_FC2) and phono3py_disp.yaml. This step is not mandatory, but you can avoid calculating fc2 and fc3 at every run time when reading force constants from these files with --fc3 and --fc2 options.
