Hi
I have a problem in making a periodic boundary condition, it happens when i try to make my mesh finer. Fluent gives me this Error Warning: differing number of faces on these threads. computed translation deltas: 0.100000 -0.000126 zone 20016: matched 83 out of 83 faces. zone 30021: matched 83 out of 84 faces. Error: Failed to make zones periodic. Error Object: #f Thank you. |

Hi,
This is because of the mismatch of cell centroid of two boundary u are trying to make conformal periodic BC. U first convert the boundary as interface BC and then go to interface panel and make them periodic (Non-conformal). Non-conformal periodic BC also gives the good result. |

first make the boundary as interface BC to which u want to make periodic and see the web page. it may be halp u.

Hi!
To make a conformal periodic BC you can use the "Match Control" option inside Ansys Mesher. Regards |
