hello everyone
i'm trying to study flow behaviour of an airfoil with a dimple on it ..i have done with the meshing .but, when i checked the mesh in fluent it says mesh check failed.. please help me with this..

when i do mesh check it shows as below

Domain Extents:
x-coordinate: min (m) = -1.299804e-01, max (m) = 2.100000e-01
y-coordinate: min (m) = -1.300000e-01, max (m) = 1.300000e-01
Volume statistics:
minimum volume (m3): 8.127845e-10
maximum volume (m3): 1.229440e-05
total volume (m3): 8.112471e-02
Face area statistics:
WARNING: invalid or face with too small area exists.
minimum face area (m2): 0.000000e+00
maximum face area (m2): 5.081937e-03
Checking mesh..........
WARNING: left-handed faces detected on zone 12: 350 right-handed, 2 left-handed........
WARNING: The mesh contains high aspect ratio quadrilateral,
hexahedral, or polyhedral cells.
The default algorithm used to compute the wall
distance required by the turbulence models might
produce wrong results in these cells.
Please inspect the wall distance by displaying the
contours of the 'Cell Wall Distance' at the
boundaries. If you observe any irregularities we
recommend the use of an alternative algorithm to
correct the wall distance.
Please select /solve/initialize/repair-wall-distance
using the text user interface to switch to the
alternative algorithm.
........
Done.

WARNING: Mesh check failed.

To get more detailed information about the mesh check failure
increase the mesh check verbosity via the TUI command
/mesh/check-verbosity.
Fluent can also try to fix the mesh check problems via the TUI command
/mesh/repair-improve/repair.
Interrupting...
Done.

probably you have some collasped/overlapping edges/blocks/faces. Mesh distriubtion is also not good.

Show some pics in vicinity of dimple.


PS. By which formula you are calculating the depth of dimple and how much percent of boundary layer thickness?
