Hi dear friends,
I have a problem in Ansys Fluent.
When I check mesh,the the following information is saw:
x-coordinate: min (m) = -1.152834e-01, max (m) = 1.152834e-01
y-coordinate: min (m) = -7.058838e-18, max (m) = 1.125000e+00
z-coordinate: min (m) = -3.012500e-01, max (m) = -1.847759e-01
minimum volume (m3): 1.086857e-17
maximum volume (m3): 2.033040e-06
total volume (m3): 2.225942e-02
Face area statistics:
WARNING: invalid or face with too small area exists.
minimum face area (m2): 1.225212e-13
maximum face area (m2): 8.780503e-04
WARNING: left-handed faces detected on zone 20: 4618032 right-handed, 36 left-handed.
Info: Used modified centroid in 13 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
WARNING: Mesh check failed.
To get more detailed information about the mesh check failure
increase the mesh check verbosity via the TUI command
Fluent can also try to fix the mesh check problems via the TUI command
Now, What do I do? can I set up Fluent in this situation?
Where is command of /mesh/repair-improve/repair in fluent?
I generated mesh in Gambit and it is structure and very good and I spent a lot of time for generating mesh.
I an grateful that guide me. really I am not able to solve it.

You can access the address fluent has shown to you via TUI
only type "mesh" then enter, then "repair-improve" and...
but usually it couldn't help you,
It's often better to check your mesh again, I think your minimum volume is too low!
