WebImportant: The supercell used to calculate the MD has to be an integer multiple of the cell used in phonopy calculation. The order of the atoms within the cell has to be kept in both cells to work properly. A convenient way is to use Phonopy to generate the supercell (SPOSCAR) to be used in the MD. $ phonopy -d --dim="2 2 2" WebAug 9, 2024 · module load phonopy/1.11.10.4 In the pre-process, supercell structures with (or without) displacements are created from a unit cell fully consiering crystal symmetry. To obtain supercells (2 × 2 × 2) with displacements, run phonopy: 1 phonopy -d --dim="2 2 2" You should find the files, SPOSCAR, disp.yaml, and POSCAR- {number} as follows: 1
