Polygon Surface Mesh:Backward facing step in a duct This study focuses on a 3D backward facing step within a duct. The duct geometry was decomposed into 6-faced blocks so it could support a hexahedral mesh as well as the more general tetrahedral and polyhedral meshes. Meshes Slices through th...
Open Volumetric Mesh-An Efficient Data Structure for Tetrahedral and Hexahedral Meshes 数据结构六面体网格网格划分开放式四面体种用拓扑元素可扩展性This work introduces a scalable and efficient topological structure for tetrahedral and hexahedral meshes. The design of the data structure aims at maximal ...
tetrahedral meshhexahedral meshDesign and analysis softwares are the backbone of todays rapidly developing engineering world. Due to the unmatched flexibility and fair accuracy of these tools, a modern design engineer relies heavily on these techniques. However, it is very important to note that one...
aInitially, a hexahedral element was used as its accuracy is higher than that of tetrahedral element but the mesh failed as the model surface became rougher. 最初,一个hexahedral元素使用了,因为它的准确性那高于四面体元素,但滤网无法作为式样表面变得更加粗砺。 [translate] ...
meshSizeattribute to only affect the mesh size in narrow regions. Another alternative is using aSweptmesh operation for the thin parts of a geometry. The resulting hexahedral or prism elements usually have better element quality compared to the unstructured mesh after scaling the geometry. Consider ...

Mesh optimizationMesh untanglingWhisker weavingWe investigate a well-motivated mesh untangling objective function whose optimization automatically produces non-inverted elements when possible. Examples show the procedure is highly effective on tetrahedral meshes and on many hexahedral meshes constructed via ...
