IEA meeting

International Energy Agency Technology Collaboration Programme for Advanced Fuel Cells, Modelling Annex (Annex 37)

Meeting: Vienna House Easy Braunschweig | Salzdahlumer Strasse 137 | DE – 38126 Braunschweig, 14 March 2018, 9:00-14:00.

The synthesis of well-written open-source CFD software has stimulated activities in electrochemical applications by members. The IEA Modelling Annex,, coordinates the activities and developments of the group, fostering communication, in an aligned manner. Present activities are focused on continuum-level models and codes, which must be open-source and cost-free. The Annex provides a platform for joint development, and exchange of ideas. An important related activity is validation and verification, such as ‘round-robin’ tests. All delegates to ModVal 2019 are invited to attend this post-conference meeting as guests.
