Film on air quality simulation (20 February 2008)

An introductive film on air quality simulation has been produced by INRIA communication team, at the initiative of École des ponts, EDF R&D and INRIA. It is aimed at a general public and lasts approximately 9 minutes. It is only available in French at the moment, but an English version will be released in the near future.

•   Film at a 720x406 resolution (48 Mo).

Polyphemus on InriaGforge (15 February 2008)

InriaGforge is a collaborative development tool which offers mailing-lists, trackers, version control system, etc.

Please visit Polyphemus InriaGForge page . It primarily contains:

• two trackers:
  • one for bugs 
  • one for feature requests 
  Anyone can submit new items to these trackers.
• two mailing lists  :
  • polyphemus-announce: receive news about Polyphemus (for instance release of versions). To subscribe, click here   and fill in the form.
  • polyphemus-help: send an e-mail to polyphemus-help@lists.gforge.inria.fr for support. You can ask questions without being subscribed to the list.
• Subversion repository for the source and the documentations. We moved our SVN repository there in order to allow more people to develop on Polyphemus.
