Anyone have idea??
 

Hi everyone, this warning is appear when I was checking my grid in fluent, have any solution to solve it??

Warning: The mesh contains very high aspect ratio 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
Please select /solve/initialize/repair-wall-distance
using the text user interface to switch to the
alternative algorithm.


WARNING: non-positive volumes exist.

try to avoid sharp edges or high complexity feature on the model.
Normally high screwness will happen on high complex feature.
