WebPerform a phonon calculation#. Setting up a phonopy calculation is similar to settings up a relaxation (or any other workflow supported by FHI-vibes).To ensure that our physical settings don't change, we will copy the relaxation.in obtained in the previous part of the tutorial to the new working directory and rename it to phonopy.in.Please delete the … 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"

WebOverview. The Phonopy Python package provides a simple interface for extracting vibrational and thermal properties of materials from VASP output. This tutorial shows how to use VASP and Phonopy for phonon density of states, dispersion, and free energy calculations. We will use bulknn MoS 2 2 as an example. WebWhen lattice parameters of unit cell (set by POSCAR) are the column vectors of a u, b u, and c u, those of supercell, a p, b p , c p, are determined by, ( a p b p c p) = ( a u b u c u) M _ p. M p is a change of basis matrix and so M p − 1 must be an integer matrix.
