All Hexahedral Meshing of Multiple Source, Multiple Target, Multiple Axis Geometries Via Automatic Grafting and Sweeping
… a second volume. In this manner it is useful for meshing multi-axis geometry in that a single axis can be meshed with sweeping and then secondary axes can be grafted on. By creating an algorithm for automatically performing these processes, the base set of geometry that can be automatically meshed …

Adaptive Frame Fields for Polycube Generation and Quad Simplification
Hexahedral (hex) meshing is the problem of approximating a 3-dimensional volume with cube-like structures, and is used to discretize arbitrary volumes to solve PDEs. The structure of a hex mesh is largely guided by its singular graph. For a hex mesh to have good quality, the hexes must have …

3D FE simulation of the welding process to optimise residual stress profiles in complex geometries
… welded structures, a newly developed all-hexahedral meshing technique was employed to mesh the complex intersection area in a tee branch junction. The moving heat source and filler material deposition were simulated by assigning reactivated elements with a volumetric heat flux progressing …

AEROMECHANICS OF A DOUBLE ANHEDRAL TIP COMPOSITE ROTOR: EXPERIMENT AND MODELING
… 3-D model was developed with CATIA (CAD), Cubit (hexahedral meshing), and X3D (aeromechanics). The 3-D CAD was constructed with guidance from Boeing to ensure the geometry was representative of a modern rotor yet generic enough to be open source for U.S. Gov-industry-academia joint study. The …

Integrable symmetric fields in computational design : from stable woven shells to seamless parameterizations
… grand challenge of developing a robust hexahedral mesh generation package, and state of the art approaches employ a pipeline where this mesh generation process is guided by an orientation field. In each case, a powerful algorithmic pipeline involves first designing a continuous direction …

Domain decomposition for hexahedral mesh generation using singularity lines
Generating automatically a hexahedral mesh for a 3D domain of arbitrary complexity is a challenging problem that has puzzled the research community considerably. As opposed to tetrahedral mesh generation, there is no existing algorithm that can operate with the push of a button and produce the …
