Phonopy is an open source package of phonon calculations based on the supercell approach.
We are preparing to release a major update of phonopy with anharmonic phonon calculations: phonon lifetime, lattice thermal conductivity, etc. Currently the code is under the status of closed-beta. This is for the test and optimization of the user interface with the help of test users. Although we plan to release an open-beta with the manual on the web soon, we are ready to distribute the beta-manual in pdf via direct e-mail if we receive contacts from anybody who can be a test user. Some more information on the closed-beta release and how to contact is found at this post in the phonopy mailing list.
Selected features of harmonic and quasi-harmonic phonons are:
