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 !!
