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. WebWelcome to phonopy # Phonopy is an open source package for phonon calculations at harmonic and quasi-harmonic levels. Phono3py is another open source package for phonon-phonon interaction and lattice thermal conductivity calculations. See the documentation at http://phonopy.github.io/phono3py/
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 … WebMay 6, 2014 · Dear All, Using the command "phonopy --symmetry", two files BPOSCAR and PPOSCAR are created.
