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)
Mesh (non-empty, non-wedge) directions (1 1 1)
Mesh (non-empty) directions (1 1 1)
Boundary openness (-2.91342e-10 5.64332e-11 -4.06066e-09) OK.
***Open cells found, max cell openness: 4.45478e-05, number of open cells 74
<<Writing 74 non closed cells to set nonClosedCells
Minumum face area = 3.61057e-08. Maximum face area = 1.94527e-06. Face area magnitudes OK.
Min volume = 6.1867e-12. Max volume = 1.5632e-09. Total volume = 4.88689e-05. Cell volumes OK.
Mesh non-orthogonality Max: 59.6733 average: 3.7892
Non-orthogonality check OK.
Face pyramids OK.
Max skewness = 1.39085 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!
