In ANSYS Meshing, the boco means that your mesh is generated with periodic nodes...
However, once you get to the solver, you may still need to setup your bocos (inlet, outlet, periodic, symmetry, etc.) It does not happen automatically. If I have mis-understood the question, please try again... In the mean time... Please help guide development at ANSYS by filling in these surveys Public ANSYS ICEM CFD Users Survey This second one is more general (Gambit, TGrid and ANSYS Meshing users welcome)...

Hi Simon,
You have helped me in the past and its greatly appreciated. Originally I tried to mesh this in ICEM but I couldn't get the blocking to workout. So I moved to workbench. From images you can see BC is accepted and mesh generated in WB, but then fluent doenst recongnize and I dont have the option to call Periodic. Also I have matched meshed the periodic faces and inserted a cylindrical coord system. Thanks, Brian |

Thanks, Brian |

Hi,
You just have to specify that these zones are periodic (in FLUENT): You write : mesh then modify-zones then make-periodic enter zones ID, and answer yes to the questions. Do not forget to specify a cylindrical coordinates system during building your mesh. |
