You should find files, SPOSCAR, disp.yaml, and POSCAR-{number}. SPOSCAR is the perfect supercell structure, disp.yaml contains the information on displacements, and POSCAR-{number} are the supercells with atomic displacements.

WebThe files of supercells with atomic displacements like as POSCAR-001, POSCAR-002, ..., are created in current directory (the file format and names are different in WIEN2k mode.) by running phonopy. The files disp.yaml and SPOSCAR are also created. The file SPOSCAR is the perfect supercell that contains no atomic displacement.
