Hexahedral-dominant meshingSweepingGeometric reasoningThis paper describes an automatic method for identifying thin-sheet regions (regions with large lateral dimensions relative to the thickness) for complex thin-walled components, with a view to using this information to guide the hexahedral (hex) ...

The resulting decomposition delivers a substantial step towards automatic hexahedral meshing for complex thin-walled geometries. It is proposed that hexahedral meshes be applied to the identified thin-sheet regions by quad meshing one of the faces bounding the thin-sheet region and sweeping it through...
Hexahedral (hex) meshes can be generated for CAD models of complex thin-walled components by isolating thin-sheet and long-slender regions, quad meshing one of the bounding faces, and sweeping the quad mesh through the volume to create hex elements. Continuing the work in Sun et al. (Proc ...

Hexahedral dominant meshingThis paper describes an automatic method for identifying thin sheet regions in a complex solid model. The main purpose of thin sheet identification is to ease the current situation of hexahedral meshing for complex geometry in the aerospace industry, since swept hexahedral ...
Hexahedral volume meshingCavity meshingTetrahedraBoundary layersA parametric meshing technique is presented with special emphasis to singularities in the parametric mapping. Singularities are locations where the parametric mapping is highly distorted or even singular. In a NURBS context, this arises when ...
