Advanced boundary layer meshing

Participants: F. Alauzet [correspondant], J. Castelneau, L. Marechal, D. Marcum and A. Loseille

We design a new method to generate structured boundary layer meshes which are mandatory to accurately compute compressible flows a high Reynolds number (several millions). It couple the specification of the optimal boundary layer from the geometry boundary and moving mesh techniques to extrude the boundary layer in an already existing mesh. The main advantage of this approach is its robustness, i.e., at each step of the algorithm we have always a valid mesh.
