WebPhonopy can easly generate a super cell with the desired size using the command: $ phonopy -d --dim="2 2 2" -c POSCAR_unitcell. This generates a SPOSCAR file containing a 2x2x2 super cell of POSCAR_unitcell file. Alternativelly, DynaPhoPy can also be used to generate a super cell in VASP POSCAR format using the command: $ dynaphopy input_file … WebHowever, this is not possible when using force constants from e.g. phonopy. We recommend that you compare the dispersion between the original force constants, the ones produced by hiphive, and the ones produced by hiphive after enforcing the rotational sum rules. ...

http://abelcarreras.github.io/DynaPhoPy/usage.html WebSymmetries are searched by attempting possible symmetry operations to the crystal structure and checking if the crystal structure after the symmetry operation is overlapping to the original crystal structures. In this analysis, a tolerance of distance is used to tolerate small deviation of overlapping. This tolerance is the user’s choice.
