● 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”的前提条件并不完全公...

I see you always reccomend the use of HEX instead of TET, this is ofcourse true and the ideal situation is always using HEX mesh, but most of the geometries I encounter are way too complex for HEX meshing in 3D solid elements (different wall thickneses, crazy curved surfaces etc.), ...
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 ...
