Phonopy lo-to
WebWork flow of phonopy is shown schematically. There are two ways to calculate, (1) atomic forces from finite displacements and (2) given force constants. You can choose one of them. Forces on atoms or force constants are calculated by your favorite calculator (shown by the octagons in the work flow). WebTo install them just do: $ python setup.py install --user. In the folder where you ran anaddb you will find a netCDF file (if you compiled Abinit with netCDF support) with the name …
