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...

Hexahedral elements, on the other hand, can be subdivided anisotropically without mesh quality problems. Furthermore, hexahedral meshes yield more accurate solutions than their tetrahedral counterparts for the same number of edges. Both the tetrahedral and hexahedral mesh adaptation procedures use edge-...

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]...
