 FESTIM was originally developed at the `Institute for Magnetic Fusion Research (IRFM) <https://irfm.cea.fr/en/index.php>`_ and the `Process and Materials Sciences Laboratory (LSPM) <https://www.lspm.cnrs.fr/en/home/>`_.
 Various research institutions and private companies now contribute actively to FESTIM's development.
