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.

In this analysis, a tolerance of distance is used to tolerate small deviation of overlapping. This tolerance is the user’s choice.
