The module has been implemented for the unstructured finite-volume solver DLR-TAU. This methodology aims to reduce the influence of the user expertise in mesh generation. The desired accuaracy of the functional may be achieved through an automatic process of mesh adaptations and error estimation without, in principle, any user intervention.
