CFD Online Discussion Forums - Cyclic BC on cylinder: "Cannot match vectors to faces on both sides of patch"

Hi everyone,

I built an axis-symmetric wedge and selected cyclic BC on the wedge faces. BlockMesh actually builds the mesh, but returns an error:

Code:

--> FOAM Serious Error : 

    From function cyclicPolyPatch::order(const primitivePatch&, labelList&, labelList&) const

    in file meshes/polyMesh/polyPatches/constraint/cyclic/cyclicPolyPatch.C at line 1402

    Patch:anticlock : Cannot match vectors to faces on both sides of patch

    Perhaps your faces do not match? The obj files written contain the current match.

Nevertheless, checkMesh returns "Mesh OK".
Can anyone explain what it means?

I am attaching the blockMesh file together with a snapshot of the mesh and the output of blockMesh and checkMesh commands.

Thank you in advance :)
