ANSYS cutCell method produced nonClosedCells
 
Dear OpenFOAMers,

I used ANSYS Workbench V14. The fluid domain was sliced into 3 pieces, then, "formed a new part". Then, I used cutCell method to mesh the domain, exported to fluent format.

Then, I used fluent3DMeshToFoam to convert the mesh to OpenFOAM format. Then, I used mergeOrSplitBaffles to merge some faces due to slicing in Workbench. When I did checkMesh, I got:

Checking geometry...
Overall domain bounding box (-0.0665 0 -2.22045e-19) (0.0125 0.00912567 0.104)

***Open cells found, max cell openness: 4.45478e-05, number of open cells 74

Non-orthogonality check OK.
Face pyramids OK.

Coupled point location match (average 0) OK.

Failed 1 mesh checks.

I am wondering if anyone experienced the same issue? And, is there a solution to this problem? Thanks!
