Phonopy tutorial
WebThe phonopy Python package is a common tool used to evaluate phonons for a given atomic configuration. Atomic configurations are represented in phonopy by the phonopy.Atoms class, which is based on the ase.Atoms class. WebUsing Phonopy the harmonic forces can be calculated as detailed in phonopy online tutorial. During the calculation, a SPOSCAR file which contains a super cell of the original POSCAR file is generated. This file can be used to calculate the MD in VASP. ... Phonopy can easly generate a super cell with the desired size using the command:

WebDec 10, 2024 · 1 Answer Sorted by: 6 +50 Phonopy creates different POSCAR file in which atoms are perturbed, as you are running each POSCAR for NSW=1 or 0, IBRION=-1 will be correct choice. For NSW=1 or 0 , only one self consistency loop will run with no update in ion position , all IBRION tags are equivalent. IBRION=-1: no update.
