Ccm problem conversion
hi,
i try to use mesh done with starcd at ccm format this mesh work in starcd and have done results i try to use it with openfoam but i have got a lot of mistakes Checking topology... Boundary definition OK. Point usage OK. ***Faces not in upper triangular order. <<Writing 1 unordered faces to set upperTriangularFace Topological cell zip-up check OK. Face vertices OK. ***Number of duplicate (not baffle) faces found: 3 ***Number of faces with non-consecutive shared points: 15 <<Writing 34 faces with incorrect edges to set edgeFaces Number of regions: 1 (OK). hecking geometry... Domain bounding box: (-0.15556 -0.155535 -0.208931) (0.155567 0.155559 0.0878565) Boundary openness (2.70101e-17 1.69899e-15 -9.76175e-16) OK. Max cell openness = 3.00293e-16 OK. Max aspect ratio = 113.781 OK. Minumum face area = 1.17018e-10. Maximum face area = 3.77982e-05. Face area magnitudes OK. Min volume = 6.32778e-15. Max volume = 2.91443e-07. Total volume = 0.0121013. Cell volumes OK. Mesh non-orthogonality Max: 120.41 average: 15.7579 *Number of severely non-orthogonal faces: 6399. ***Number of non-orthogonality errors: 8. <<Writing 6407 non-orthogonal faces to set nonOrthoFaces ***Error in face pyramids: 104 faces are incorrectly oriented. <<Writing 103 faces with incorrect orientation to set wrongOrientedFaces ***Max skewness = 41.9298, 194 highly skew faces detected which may impair the quality of the results <<Writing 194 skew faces to set skewFaces Min/max edge length = 1.28144e-06 0.00530942 OK. *There are 8354 faces with concave angles between consecutive edges. Max concave angle = 89.9293 degrees. <<Writing 8354 faces with concave angles to set concaveFaces Face flatness (1 = flat, 0 = butterfly) : average = 0.990754 min = 0.0140377 *There are 2291 faces with ratio between projected and actual area < 0.8 Minimum ratio (minimum flatness, maximum warpage) = 0.0140377 <<Writing 2291 warped faces to set warpedFaces Failed 5 mesh checks. how is it possible to have a skewness of 41.92 and a max non-orthogonality of 120? are there some mistakes that don't prevent the computation? is it possible to correct some mistakes with openFoam? is there a starcd format which is better for conversion? best regards |
