pyiron - an integrated development environment (IDE) for computational materials science. It combines several tools in a common platform:

  • Atomic structure objects – compatible to the Atomic Simulation Environment (ASE).

  • Atomistic simulation codes – like LAMMPS and VASP.

  • Feedback Loops – to construct dynamic simulation life cycles.

  • Hierarchical data management – interfacing with storage resources like SQL and HDF5.

  • Integrated visualization – based on NGLview.

  • Interactive simulation protocols - based on Jupyter notebooks.

  • Object oriented job management – for scaling complex simulation protocols from single jobs to high-throughput simulations.

pyiron (called pyron) is developed in the Computational Materials Design department of Joerg Neugebauer at the Max Planck Institut für Eisenforschung (Max Planck Institute for iron research). While its original focus was to provide a framework to develop and run complex simulation protocols as needed for ab initio thermodynamics it quickly evolved into a versatile tool to manage a wide variety of simulation tasks. In 2016 the Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) joined the development of the framework with a specific focus on high throughput applications. In 2018 pyiron was released as open-source project.

Note

pyiron 0.X – Disclaimer: With the first open source release of pyiron under the BSD license we provide a fully functional core platform. We are currently working on finalizing various plugins, e.g. to enhance high throughput simulations, for Computational Phase Studies, and Electrochemistry and Corrosion. The code is published on Github.org, PyPi.org and Anaconda.org

Explore pyiron

We provide various options to install, explore and run pyiron:

  • Workstation Installation (recommeded): for Windows, Linux or Mac OS X workstations (interface for local VASP executable, support for the latest jupyterlab based GUI)

  • Mybinder.org (beta): test pyiron directly in your browser (no VASP license, no visualization, only temporary data storage)

  • Docker (for demonstration): requires Docker installation (no VASP license, only temporary data storage)

Join the development
