Reliable Whisker Weaving via Curve Contraction
Whisker Weaving is an advancing front algorithm for all-hexahedral mesh generation. It uses global information derived from grouping the mesh dual into surfaces, the STC, to construct the connectivity of the mesh, then positions the nodes afterwards. Currently we are able to reliably generate hexahedral meshes for complicated geometries and surface meshes. However, the surface mesh must be modified locally. Also, in large, highlyunstructured meshes, there are usually isolated regions where hex quality is poor. Reliability has been achieved by using new, provable curve-contraction algorithms to sequence the advancing front process. We have also demonstrated that sheet moving can remove certain types of invalid connectivity. keywords. hexahedra, mesh generation, advancing front, topology, curve contraction
