We cover the whole spectrum of alternative approaches to mesh generation, as well as post-processing algorithms for connectivity editing and mesh optimization. For each technique, we highlight capabilities and limitations, also pointing out the associated unsolved challenges. Recent relaxed approaches, aiming to generate not pure-hex but hex-dominant meshes, are also discussed. The required background, pertaining to geometrical as well as combinatorial aspects, is introduced along the way.</jats:p>","lang":"eng"}],"author":[{"full_name":"Pietroni, Nico","first_name":"Nico","last_name":"Pietroni"},{"last_name":"Campen","id":"114904","orcid":"0000-0003-2340-3462","full_name":"Campen, Marcel","first_name":"Marcel"},{"first_name":"Alla","full_name":"Sheffer, Alla","last_name":"Sheffer"},{"last_name":"Cherchi","full_name":"Cherchi, Gianmarco","first_name":"Gianmarco"},{"last_name":"Bommes","full_name":"Bommes, David","first_name":"David"},{"last_name":"Gao","first_name":"Xifeng","full_name":"Gao, Xifeng"},{"last_name":"Scateni","full_name":"Scateni, Riccardo","first_name":"Riccardo"},{"last_name":"Ledoux","full_name":"Ledoux, Franck","first_name":"Franck"},{"full_name":"Remacle, Jean","first_name":"Jean","last_name":"Remacle"},{"last_name":"Livesu","first_name":"Marco","full_name":"Livesu, Marco"}],"extern":"1","department":[{"_id":"969"}],"date_created":"2025-06-23T10:36:34Z"}
