Hello forum !
First of all I am new to Openfoam. I have a mesh using GMSH, extrude (to get 3D domain) and gmshToFoam. At first, its all looks nice until i do « checkMesh » and all of enjoyment dissapear. I have this following error
Code:
***High aspect ratio cells found, Max aspect ratio: 3.35195e+155, number of cells 67
<<Writing 67 cells with high aspect ratio to set highAspectRatioCells
***Zero or negative face area detected. Minimum area: 0
<<Writing 137 zero area faces to set zeroAreaFaces
***Zero or negative cell volume detected. Minimum negative volume: 0, Number of negative volume cells: 67
<<Writing 67 zero volume cells to set zeroVolumeCells
Mesh non-orthogonality Max: 90 average: 34.0927
***Number of non-orthogonality errors: 37.
<<Writing 37 non-orthogonal faces to set nonOrthoFaces
Face pyramids OK.
***Max skewness = 1.78771e+154, 135 highly skew faces detected which may impair the quality of the results
<<Writing 135 skew faces to set skewFaces
Coupled point location match (average 0) OK.
Failed 5 mesh checks.
End
There is no way I can get a ratio that high since I dont have that much distance in my domain. Somehelp might be usefull to me, thanks !!
