Autogrid Mesh to openFoam

Dear Numeca Team,

I am currently working on benchmarking CFD results for a turbomachinery simulation. As part of this process, I am attempting to use a previously generated mesh for OpenFOAM. After converting the mesh in AutoGrid5 and checking its quality with the checkMesh command in OpenFOAM, I encountered the following error: “Distance between the center of patch XY and transformed center of patch UV is greater than the match tolerance of XY for the patch.” (Note: Patches XY and UV are located on either side of the periodicity.) I suspect this issue is related to the options chosen during the AutoGrid setup. I’ve tried modifying the size of the overall domain to fit the rotor and tested both matching and non-matching periodicity settings, but unfortunately, none of these attempts resolved the issue. I would greatly appreciate any guidance or suggestions on how to address this

Please provide information about the Fine Turbo and OpenFoam software versions.
Please navigate to support.cadence.com, where you can search for the "AUTOGRID" manual and go through the "Export—> OpenFOAM."
Referring to your error, I am attaching some parts of the documentation. Please go through them.

Thank you for the answer, I am certainly aware of this fact. These recommendations are the reason I altered my meshing and why I used the advanced skewness control. But the issue of the bad cells arises AT first cell at the blade surface.

It looks like the cells are sheared for some reasons.
