Summary Local grid refinement for unstructured meshes is a common approach to improve the accuracy of a solution for a given CFD problem or to reduce the amount of needed points for a numerical calculation. As part of the DLR-TAU code the Adaptation provides a hierarchical refinement and de-refinement tool for 2D and 3D hybrid grids. The object of this tool is to adapt the grid automatically to a given solution. This article described the major components of the tool, the grid refinement with surface approximation and the y+ adjustment along wall-normal lines. Furthermore an overview of the used sensor functions is given, which are available for the detection of the local refinement and de-refinement.
