Hi,

I ran checkMesh on a mesh generated by snappyHexMesh. The mesher converged without problems, but running checkMesh gave:

Checking geometry...
Domain bounding box: (0 0 0) (3.2 2 2.4)
Boundary openness (3.31594e-18 1.11805e-15 3.12204e-17) OK.
Max cell openness = 2.70321e-16 OK.
Max aspect ratio = 2.52179 OK.
Minumum face area = 1.40343e-05. Maximum face area = 0.00644646. Face area magnitudes OK.
Min volume = 2.14557e-07. Max volume = 0.000515752. Total volume = 15.3453. Cell volumes OK.
Mesh non-orthogonality Max: 45.4347 average: 11.2568
Non-orthogonality check OK.
Face pyramids OK.
Max skewness = 1.27883 OK.
*There are 454 faces with concave angles between consecutive edges. Max concave angle = 69.111 degrees.
<<Writing 454 faces with concave angles to set concaveFaces
Face flatness (1 = flat, 0 = butterfly) : average = 0.999785 min = 0.796655
*There are 1 faces with ratio between projected and actual area < 0.8
Minimum ratio (minimum flatness, maximum warpage) = 0.796655
<<Writing 1 warped faces to set warpedFaces

Using foamToVTK, then paraview, I was unable to see the cellSets mentionned.

I then converted the file in Fluent msh format (hoping to be able to vizualize bad cells there) and a calculation converged on this mesh. So I am wondering if it is really that bad.

How can I vizualize the sets produced by checkMesh ?

I found a solution:

foamtToVTK -faceSet concaveFaces
