aimsgb

Introduction

aimsgb, an efficient and open-source Python library for generating atomic coordinates in periodic grain boundary models. It is designed to construct various grain boundary structures from cubic and non-cubic initial configurations. A convenient command line tool has also been provided to enable easy and fast construction of tilt and twist boundaries by assigining the degree of fit (Σ), rotation axis, grain boundary plane and initial crystal structure. aimsgb is expected to greatly accelerate the theoretical investigation of grain boundary properties and facilitate the experimental analysis of grain boundary structures as well.
