The paper presents the anisotropic adaptation algorithm applied to simulations of high-Reynolds turbulent compressible flows past complex 3D geometries. The adaptive algorithm relies on anisotropic grid-cell spacing definition provided by the error estimator in a form of a metric field. The error estimator is based on the Hessian of the solution with additional terms used to improve the grid spacing in the regions of high viscous shear forces. The adaptive algorithm is used for the two testcases the Onera M6 wing and the High Lift Prediction Workshop 1 trap wing.
