The 5th Open Source CFD International Conference 2011, organised by ICON, took place in Chantilly, France on the 3rd & 4th November. Delegates found out about the current best practices and state-of-the-art in Open Source CFD and associated technologies, attending two keynotes and choosing from 32 presentations, poster session, exhibition and discussion breaks. The conference welcomed delegates to Chantilly (near Paris) to meet, listen and debate with attendees from academia and various industries including oil & gas, consumer products, automotive, motorsport, marine, process, energy, nuclear safety, industrial productivity solutions, consulting engineering, tobacco industry and glass manufacture. It gave plenty of opportunities for networking and was very well received as a valuable, stimulating and enjoyable event.

Keynotes from Volkswagen and Politecnico di Milano opened a two-day packed agenda with presentations showing innovative work in reacting, multiphase, environmental and compressible LES flows, acoustic analysis, flow in rotating machinery, CFD in Medicine and external aerodynamics.

Congratulations to Dr. Stefan Blume who won the ICON FOAMpro Design-an-Aircraft competition. Conference delegates were asked to define the optimal parameters for an aircraft with minimal drag using ICON FOAMpro's built-in GUI. Second and third place winners were Jiri Furst (Czech Technical University in Prague) and Dr. Octavian Frederich (Volkswagen).
