Anisotropic Mesh Adaptation for Transient Flows Simulations

Unstructured mesh adaptation has already revealed very efficient for computing an accurate solution in a reasonnable amount of time on current PC architectures. Two features are still missing in the adaptation scheme: (i) the creation of arbitrary anisotropic meshes and (ii) the capture of transient phenomena. Therefore, in this paper, we propose a global scheme suitable to compute steady-state as well as transient problems, based on anisotropic mesh adaptation. Several examples of numerical simulations in CFD are provided to emphasize the efficiency of the proposed approach.
