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. WebSince phono3py is controlled via a command line interface the force constant matrices have to be written to file. fcs.write_to_phonopy('fc2.hdf5') fcs.write_to_phono3py('fc3.hdf5') write('POSCAR', prim) This concludes the part that involves hiPhive.
