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. WebAug 12, 2024 · Without FORCES_FC2, how can fc2.hdf5 be obtained? FORCES_FC2 is optional. fc2.hdf5 is generated from FORCES_FC3. When we want to use a larger supercell for fc2 than that for fc3, i.e., different supercell sizes for fc2 and fc3, FORCES_FC2 is used together with the --dim-fc2 option. fc3.hdf5 and fc2.hdf5 are not created from … country wifi
