19.10 Geometry-Based Adaption

The purpose of adaption is to produce a mesh that is fine enough and adequately represents all important features of the geometry. However, when you have a coarse mesh of a geometry that has curved profiles and sharp corners, the adapted mesh may not recover the curved profiles and corners at the perimeter of the geometry. In such cases, use geometry-based adaption to reconstruct the geometry (or to recover the finer details of the geometry at its extends) along with performing the adaption process.
