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.
