Hey Foamers,
I did a mesh using CfMesh. Than I tried to improve it using "ImproveMeshQuality". In the end, I had a worst mesh. Here you can see the checkMesh file: before: Max cell openness = 7.35622e-16 OK. Max aspect ratio = 29.7317 OK. Minimum face area = 3.92408e-13. Maximum face area = 1.47856e-07. Face area magnitudes OK. Min volume = 1.60163e-18. Max volume = 3.43724e-11. Total volume = 3.3578e-06. Cell volumes OK. Mesh non-orthogonality Max: 84.9321 average: 12.8083 *Number of severely non-orthogonal (> 70 degrees) faces: 309. Non-orthogonality check OK. <<Writing 309 non-orthogonal faces to set nonOrthoFaces Face pyramids OK. ***Max skewness = 4.04614, 2 highly skew faces detected which may impair the quality of the results <<Writing 2 skew faces to set skewFaces Coupled point location match (average 0) OK. Failed 1 mesh checks. after: Overall domain bounding box (-0.0244538 -0.00600789 -0.0060014) (0.268829 0.0361308 0.00600139) Mesh has 3 geometric (non-empty/wedge) directions (1 1 1) Mesh has 3 solution (non-empty) directions (1 1 1) Boundary openness (-3.56984e-17 -1.29466e-16 -2.01585e-15) OK. Max cell openness = 4.85654e-16 OK. Max aspect ratio = 41.771 OK. Minimum face area = 1.25284e-12. Maximum face area = 1.65683e-07. Face area magnitudes OK. Min volume = 1.20562e-18. Max volume = 3.30891e-11. Total volume = 3.3578e-06. Cell volumes OK. Mesh non-orthogonality Max: 79.9838 average: 18.2811 *Number of severely non-orthogonal (> 70 degrees) faces: 797. Non-orthogonality check OK. <<Writing 797 non-orthogonal faces to set nonOrthoFaces Face pyramids OK. ***Max skewness = 7.31313, 6 highly skew faces detected which may impair the quality of the results <<Writing 6 skew faces to set skewFaces Coupled point location match (average 0) OK. Failed 1 mesh checks. End Do you have any idea in waht is wrong? Thanks a lot, Carlo |

I am seeing something similar - a lot more non-orthogonal faces.
