Adaptive models for polymeric fluid flow simulation
Alexandre Ern, Tony Lelièvre · Comptes Rendus Mathématique · 2007
We propose a new adaptive algorithm for multiscale simulations of non-Newtonian fluids. Using a posteriori error indicators, the method can switch dynamically at each timestep between a rough (macroscopic) and a detailed (microscopic) model in each cell of the mesh. The validity of the approach is tested on a plane shear flow for the FENE model of polymeric fluids.
