WebThe POSCAR format is phenomenally underspecified, and there is a lot of false information about it on the web. This section aims to clarify the crate author's interpretation of the format, based on reviewing the behavior of other libraries for VASP interop, and checking against the VASP 5.4.1 implementation.

WebIf we consider a grain boundary such as that shown in figure 4.1, the overall geometry of the boundary is defined by the orientation of the boundary plane AB with respect to one of the two crystals (two degrees of freedom) and by the smallest rotation ( ) required to make the two crystals coincident (three degrees of freedom). There are thus five
