SUMMARY:Collapsing Embedded Cell Complexes for Safer Hexahedral Meshing
DESCRIPTION:Technical Papers\n\nHendrik Brückler and Marcel Campen (Osnabr
 ück University)\n\nWe present a set of operators to perform modifications,
  in particular collapses and splits, in volumetric cell complexes which ar
 e discretely embedded in a background mesh. Topological integrity and geom
 etric embedding validity are carefully maintained. We apply these operator
 s strategically to block decompositions, so-called T-meshes or base comple
 xes, in the context of hexahedral mesh generation. This allows circumventi
 ng the expensive and unreliable global volumetric remapping step in the ve
 rsatile meshing pipeline based on 3D integer-grid maps. In essence, we red
 uce this step to simpler local cube mapping problems, for which reliable s
 olutions are available. As a consequence, the robustness of the mesh gener
 ation process is increased, especially when targeting coarse or block-stru
 ctured hexahedral meshes. We furthermore extend this pipeline to support f
 eature alignment constraints, and systematically respect these throughout,
  enabling the generation of meshes that align to points, curves, and surfa
 ces of special interest, whether on the boundary or in the interior of the
  domain.\n\nRegistration Category: Full Access\n\nSession Chair: Nicholas
