title = "Local optimization of the convergence rates of implicit time advancements for LES of complex flows",
abstract = "An improvement of an implicit scheme for Large-Eddy Simulation is proposed in this paper. This local optimization (LO) of the convergence is based on the reduction of the high computational effort per time step inherent to the use of implicit time stepping methods. Indeed, the LO is a local adpatation of the iteration number in the inner process. Moreover an implicitation of the boundary condition between two domains where the iteration number is different, is also used. This procedure is validated on two test cases. The first one is a 2D laminar vortex advection which allows us to check the potential of this LO. On a transitional boundary layer around an airfoil near stall at a chord Reynolds number of 2.1 × 106, it is shown that this procedure can be used without damaging the accuracy.",
