One of the main question faced by the large eddy simulation(LES) users is, why dynamic model works? Many authors have tried to answer this question with little sucess. In the present work we would like to show the insensitiveness of the dynamic model to the externaly introduced variation in the model coefficent, which proves the robustnessof the model. Analytical and physical reasoning for this behaviour is given by simulating the fully developed channel flow case. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
