I don't have time to look at your case, but I can tell you the two most common mistakes...

1) When selecting periodic verts, you need to get every pair. A good final check is to right click on faces (in the tree under blocking) and turn on the periodic faces option... You can do the same for Verts and quickly make sure you got it all.

2) The checks ask you to select the parts that are periodic. Often, even if the blocking is periodic, users have associated it to underlying geometry who's names are not setup in periodic pairs. For instance, on the one periodic face, all the surfaces and curves may in in the part PER1, but on the other side all the surfaces are in PER2 and the curves are in GEOM. When you run the periodic check between PER1 and PER2, it won't be a perfect match because you are missing all the line elements and nodes that formed along GEOM... I am not saying that you need all the curves in PER2, but you need to make sure you are comparing equal sets.


After that, you do need to do something tricky in Fluent to get it to apply the correct periodic boundary condition... I know I have posted that command several times before, so do a search...

Search tip: I find that a google search of the CFD-Online site finds things faster and more reliably than the CFD-Online built in search.
