The files disp.yaml and SPOSCAR are also created. The file SPOSCAR is the perfect supercell that contains no atomic displacement.

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 … WebFeb 28, 2024 · Another problem is that when I expanded the cell, I used POSCAR-00x or SPOSCAR as POSCAR for vasp calculation. After that, whether POSCAR-unitcell was used as POSCAR when running "phonopy -t -p mesh.conf" to get the thermodynamic properties.

WebSep 25, 2015 · Phonopy may be a useful tool since more features are ready to use for the properties that mesh sampling is necessary, and in this case direct space force constants via dfpt can be plugged in to phonopy. I think the role of phonopy is to provide a useful set of computations after force constants, and APIs will be more important.
