The focus of QLES will be on issues related to assessing, 
assuring, and predicting the quality of LES. The tendency 
to apply LES-methodologies to turbulent flow problems of 
significant complexity, such as arise in various 
applications in technology and in many natural flows puts 
this workshop in its timely context. Different error 
sources in LES are related to subgrid-scale modeling, to 
numerical discretization techniques, to boundary-condition 
treatments, etc. To establish the credibility of LES as a 
tool for the innovation of industrial flow applications and 
the study of complex-physics problems, a comprehension of 
the nonlinear error-accumulation arising in large-eddy 
simulations is required.

The QLES workshop invites original contributions which 
enhance the knowledge on error sources and their 
interaction in LES, and may lead to criteria for the 
prediction and optimization of simulation quality. The 
workshop will concentrate on topics such as:
- mathematical analysis and foundation for subgrid modeling,
- numerical and mathematical analysis of subgrid-scale-
model and discretization errors,
- computational error-assessment,
- high-Reynolds number modeling and error-assessment of 
near-wall flows,
- error assessment in complex applications,
- treatment of boundary conditions, inflow boundaries, 
generation of artificial turbulence, and related errors.
