http://www.nanolab.ece.ufl.edu/document/VASP_phonopy.pdf WebhiPhive is a tool for efficiently extracting high-order force constants from atomistic simulations, most commonly density functional theory calculations. It has been implemented in the form of a Python library, which allows it to be readily integrated with many first-principles codes and analysis tools accessible in Python.
