fluent网格检查出现warning，求高人指点
用pointwise画了两个相贯圆柱的结构化网格，导入fluent后check 出现以下提示
Checking mesh.................
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.
是哪里出问题了 请高手指点，对计算结构影响大不

Answer 1

你网格的横纵比过大，造成壁面拐角处网格过度质量太差。调整一下网格就好了
