“…The numerical resolution of Partial Differential Equations (PDEs) is by far the most prominent application of volumetric meshes in general, and of hexahedral meshing in particular. Nevertheless, in recent years both meshes of this kind and techniques that were originally developed in the field have been used in alternative applications, such as topology optimization and advanced manufacturing [Arora et al 2019;Stutz et al 2021;Wu et al 2021]. To this end, current themes in automatic hex-mesh generation are beneficial not only for the numerical resolution of PDEs, but may also reach a broader audience.…”
