First I chose to mesh all the model with Tet elements. Then I changed to Hex elements. But the Hex elements of the shell and the shaft didn't match on the contact surface. Then I changed the mesh so that on the contact surface of the shell and the shaft the meshes matched. Very ...
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. ...
A new computational method for creating all-hex meshes of thin-walled solids is presented. 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 ...

This 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 tetrahedral meshes, which is the focus...
