The KIM development team is pleased to announce the release of version 1.2.0 of the KIM application programming interface (API). By conforming to this API, an atomistic simulation code will seamlessly work with any KIM-compliant interatomic model written in any supported language. This release includes a completely redesigned Make system with many new features and benefits, a new NEIGH_RVEC_H NBC, a streamlined scheme for specifying a Model (or Model Driver name) and its associated “model_init()” function name, other minor changes to the api, bug fixes, portability improvements, and some new examples.
Version 1.2.0 is a fully functioning API. It has the following main features:
