Hi everyone!

Is it possible to make polyhedral cells if I've got in some domains structural hexa mesh?
In this case I got below message, but I'm not sure if this is the reason.


Checking mesh..........
WARNING: left-handed faces detected on zone 23: 632910 right-handed, 64 left-handed.
Info: Used modified centroid in 622 cell(s) to prevent left-handed faces........
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.

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.Warning:Frequency-of value for report-plot-0 is not valid. Associated report definitions will not be evaluated.
