This wiki is dedicated to the users of CFD codes developed at [http://www.coria.fr CORIA], a French combustion laboratory located in Rouen.<br/>

The CORIA-CFD plateform consists of public and private wikis and svn/trac systems to help in the development of these codes. The codes using this platform are
* [[YALES2]]
* [[SiTCom-B]]
* [[H-Allegro]]
* [[ARCHER]]

== Coming conferences ==
All the coming conferences and meetings may be found on the [[Conferences|conferences]] page.
