A multidomain/multiresolution technique is developed, with application to large-eddy simulation. A general framework for the definition of the exchange of information at the interface is proposed. It relies on the definition of some interface variables, which enables the construction of the transfer operator at the interface. The method is successfully assessed on a subsonic plane channel flow. (C) 2000 Academie des sciences/Editions scientifiques et medicales Elsevier SAS.
