Concepts for adaptive procedures have been examined. Feature detection is made more accurate by the introduction of embedded patches which act as ‘noise filters’ in the embedding procedure. A method to implement the Baldwin-Lomar algebraic turbulence model when applied to unstructured meshes proves to be accurate. Spatially varying time steps based on embedding zones can be used for unsteady problems leading to accurate results with reduced CPU times. Lastly, a conservative interface treatment is important in regions where shocks exist, but not necessarily inside boundary layers where the stretching error in the evaluation of the viscous terms may be dominant.
