●Hex与Tet体网格数量比约为1:2.5 ●Hex与Tet网格文件大小比例约为1:1.13 ●Hex与Tet求解效率比例约为1.08:1 ●Tet占据内存更大 因此,在相对“公平”的条件下,六面体网格的求解效率可以认为和四面体一致!! 相信对于大多数流体仿真工程师来讲,这是一个颠覆性的结论;当然,也有很多人会说上面所谓“公平”的前提条件...

How big an effect hex vs tet makes is problem dependent. If you are doing a simple incompressible flow it won't make much difference. If you are doing complex stuff like free surfaces, shock waves, etc etc the improved mesh quality in a hex mesh can make a huge difference. ...
This is a report of the current status of the Hex-Tet algorithm as implemented in the CUBIT toolset. The Hex-Tet algorithm begins by generating a partial hex mesh using an advancing front "Plastering" algorithm. The boundary of any remaining void is optionally "cleaned- up" to improve its ...

Tet-meshing: ANSYS vs. ICEM CFDThis article is intended to introduce you to ANSYSs new product, ICEM CFD 4.2. Now dont letthe name fool you. ICEM is much more than a CFD tool. It is a high-powered mesh generation tool that can create hex, shell, and prism meshes as well as ...
