Data Structuring and Mesh Generation
Since the notion of finite elements is often associated with that of unstructured meshes, ignoring how the latter are constructed and organized sometimes leads to the belief that the finite element method is an approximation technique far more complicated than finite differences. The first objective of this chapter is to demystify mesh generation techniques. The second is to introduce the basic notions addressed in the specialized literature, e.g., [Car97, FrG00, GeB98, KnS93, ThS98].
