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. ...
The proposed method creates an all-hex mesh in a three-step process. First, a tet mesh of the target geometric domain is created, and a layer of prism elements is inserted on the boundary of the mesh. Second, a sequence of novel topological transformations and smoothing operations is ...

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 ...
