cyclic boundary conditions

Hi, I'm trying to create cyclic boundaries for an axisymmetric cylinder with swirl. I made it only 1-cell thick (with 1 degree angle). I seem to get errors every time I try to set cyclic BCs.
I created two cyclic boundary surfaces and then try to match them. The way I create these cyclic boundary surfaces is by using the option "Create by picking surface based on Vset". What I essentially did was to select a cell on one side to create one cyclic surface and I did the same thing for the other side. I matched them next, which doesn't give me any errors. But it gives me a huge list of errors when I try to save the geometry file. Is there a simple way to do this without selecting vertices? |

Sounds like you correctly created the cyclic pairs - first make two cyclic regions then cymatch the two regions.
What are the errors? |

Thanks for the reply Pauli. I started all over again and now I'm able to save the file without any errors. Previously, I got the following error many times when I try to save the geometry.
Code:
**ERROR - CYCLIC BOUNDARIES 36000 AND 72000 ARE IN CYCLICS 1, 36001, 72001, 108001, 144001 Last edited by lost.identity; March 5, 2013 at 10:10. |
