Hiphive provides read and write functionality for force constants in a few different formats. Currently the following formats are supported. phonopy phono3py ShengBTE GPUMD We also support functionality for writing force constants and other relevant files to GPUMD format. WebMay 23, 2024 · Many different kinds of constraints can be applied in the same framework. The tradeoff is the computational demand. Phonopy has a command option to call a python wrapper of ALM (--alm), though the python wrapper doesn't support rotational invariance. I have tried to implement a hiphive interface to phonopy, but it has not yet been done.
