Hello guys,

I am simulating a 3D centrifugal compressor, geometry and mesh were created by Pointwise, and sliding mesh is selected as a method.
Problem is, when I check the mesh via Fluent 15, I see this message: (I did repair mesh, repair face handed, repair quality, ... but noting happend )

Domain Extents:
x-coordinate: min (m) = -3.266621e-03, max (m) = 1.103538e-01
y-coordinate: min (m) = -1.343171e-01, max (m) = 1.500771e-01
z-coordinate: min (m) = -1.699389e-03, max (m) = 3.278463e-01
Volume statistics:
minimum volume (m3): 8.327261e-20
maximum volume (m3): 1.387571e-07
total volume (m3): 1.132746e-03
Face area statistics:
WARNING: invalid or face with too small area exists.
minimum face area (m2): 6.173578e-16
maximum face area (m2): 1.021960e-04
Checking mesh..........
WARNING: left-handed faces detected on zone 3: 1541475 right-handed, 365 left-handed.
WARNING: left-handed faces detected on zone 9: 9839 right-handed, 1 left-handed.
Info: Used modified centroid in 94 cell(s) to prevent left-handed faces.
It is recommended that you try to fix the left-handed faces
via the TUI command
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.
