Even though many methods have been suggested to meet the challenge of all-hexahedral meshing, octree-based methods remain the most efficient from an engineering point of view. As of today, its robustness, speed and robustness are still unmatched. This paper presents advances made in the Hexotic project, especially in terms of sharp angles meshing, non-manifold geometries and adaptation.

Meshing is the process of computing, for a given surface, a representation consisting of pieces of simple surface patches, like triangles. This survey discusses all currently known surface (and curve) meshing algorithms that come with correctness and quality guarantees. Page references to other chapters are to the pages of the book.

Issues related to curvilinear mesh generation starting from a CAD model are addressed. Curvilinear mesh geometry representation in the context of p-version finite elements and its impact on the validity of curvilinear meshes is discussed. A set of meshing tools is described for generation and modification of curved meshes in three-dimensional space. An iterative algorithm for curved meshing of ...
