let to explain with picture:
attached figures show my mesh and desired mesh. if I use "my mesh", since the pipe is long (10 m) the number of mesh become too high. so I want the mesh like "desired mesh". Can you help me about this? -------------------------------- I only have these files: .cfx-.def-.out-.res |

If you are meshing in workbench, and the tube is indeed just a tube, then you can select a face at a short end and insert "mapped face meshing"

but there is a problem which is still exist. the elements on cross section are triangular, but I need rectangular mesh. I attach the picture which shows triangular mesh on cross section. If you look again to "desired mesh" picture in previous posts, you will see rectangular mesh Not triangular. |

Ah I see. Then just add a method, choose sweep and change "Free mesh type" to All Quad.
See images : http://i.imgur.com/sA2am.png http://i.imgur.com/nlyKo.png EDIT: Just occured to me that inflation of the boundary layer might be difficult if you want to keep it an hex mesh. For some reason its a hard thing for workbench meshing to do.. ICEM does this easily btw Last edited by jrunsten; August 17, 2012 at 10:47. |

Couldnt quite let this go, since I knew you wouldn't be able to get a hex mesh with inflation layers using that method. A way that will work, and that isn't that complicated, is to split the cylinder in quarters in Design Modeler, then use a Multizone meshing method. The right click on the method and choose "Inflate this method". Choose the inner and outer wall on the four inflation items and you should be good to go. See http://i.imgur.com/qf2DB.png , or http://www12.zippyshare.com/v/74996362/file.html for the archived project (v14).
If anyone know a better way, other than ICEM, I would be interested in knowing. |

Hi Jrunsten,
I am having difficulties to successfully apply Multizone meshing with inflation to an object, which is half hollow cylinder and half hollow cone. I would appreciate if you share with me your archived examples. Thank you. |
