Edge-Based Anisotropic Mesh Adaptation for CFD Applications
Résumé
This paper presents an anisotropic mesh adaptation technique relying on the length distribution tensor approach and an edge based error estimator. It enables to calculate a stretching factor providing a new edge length distribution, its associated tensor and the corresponding metric. The optimal stretching factor field is obtained by solving an optimization problem under the constraint of a fixed number of nodes. It accounts for different component fields in a single metric. With such features, the method proves to be simple and efficient and can be easily applied to a large panel of challenging CFD applications.
