Abstract

Applications of quantum chemistry have evolved from single or a few calculations to more complicated workflows, in which a series of interrelated computational tasks is performed. In particular multiscale simulations, which combine different levels of accuracy, typically require a large number of individual calculations that depend on each other. Consequently, there is a need to automate such workflows. For this purpose we have developed PYADF, a scripting framework for quantum chemistry. PYADF handles all steps necessary in a typical workflow in quantum chemistry and is easily extensible due to its object‐oriented implementation in the Python programming language. We give an overview of the capabilities of PYADF and illustrate its usefulness in quantum‐chemical multiscale simulations with a number of examples taken from recent applications. © 2011 Wiley Periodicals, Inc.
