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 … Web>phonopy --dim="a a 1" -c POSCAR-unitcell band.conf And the last process is: >phonopy-bandplot --gnuplot> PBAND.dat Then you will get PBAND.dat and you can draw figures by Origin Gnuplot Matlab etc. (The Phonopy‘s default is 51 Points between two high symmetry points) More details could be seen at Click HERE
