[求助] Fluent网格导入时check失败

大神们,请帮忙解答:
   我的网格文件在导入fluent后,check网格时出现了以下问题:
Domain Extents:
   x-coordinate: min (m) = -3.469447e-018, max (m) = 3.000000e+000
   y-coordinate: min (m) = -3.000000e+000, max (m) = 3.000000e+000
   z-coordinate: min (m) = -3.248185e-002, max (m) = 1.000000e+002
Volume statistics:
   minimum volume (m3): 8.564206e-012
   maximum volume (m3): 6.607159e-002
     total volume (m3): 1.413402e+003
Face area statistics:
   minimum face area (m2): 3.469311e-010
   maximum face area (m2): 6.311382e-001

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 distance.
         Please select /solve/initialize/repair-wall-distance
         using the text user interface to switch to the
         alternative algorithm.

Done.

WARNING: Grid check failed.

之后fluent计算结果是错的,可否帮忙看一下是什么样的错误?

第一个warning处有提示,存在纵横比过高的六面体或多面体网格,也既存在畸变率过高的网格。还是重新回到网格剖分那一步将网格质量差的部分重新划分或加密
