VASP结合Phonopy计算声子谱,微扰密度泛函方法(DFPT),计算结束后运行phonopy --fc vasprun.xml得到FORCE_CONSTANTS文件,准备band.conf文件, 运行phonopy --dim 2 2 2 -c POSCAR-unitcell band.conf得不到band.yaml文件。出现提示: "band.conf" was read as phonopy configuration file. Crystal structure was read from "POSCAR-unitcell". Unit of length: angstrom Band structure mode Settings: Force constants symmetrization: on Supercell: [2 2 2] Spacegroup: Pbcm (57) Use -v option to watch primitive cell, unit cell, and supercell structures. Force constants are read from "FORCE_CONSTANTS". Number of atoms in supercell (224) is not consistent with the matrix shape of force constants (28, 28) read from FORCE_CONSTANTS. Please carefully check DIM, FORCE_CONSTANTS, and POSCAR-unitcell. |
