The sixth ERCOFTAC Workshop on 'Direct and Large-Eddy Simulation'
(DLES-6) was held at the University of Poitiers from September 12-14,
2005. Following the tradition of previous workshops in the DLES-series,
this edition has reflected the state-of-the-art of numerical simulation
of transitional and turbulent flows and provided an active forum for
discussion of recent developments in simulation techniques and
understanding of flow physics.
