用FLUENT导入GAMBIT 网格时候出现检查错误怎么回事?出现负体积网格怎么解决修正

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.

Answer 1

出现负体积，只能在Gambit中重新划分网格，可以多分几块，或者调节网格大小，多试几次，在Gambit中先检查，没有负体积再导入Fluent计算；

Answer 2

网格质量 较差 重新划分网格！

Answer 3

应该是你的网格质量不好，equisize skew大于0.97了，这个是不允许的。你应该重新画网格。

Answer 4

楼上的大婶们有没有tgrid的32位系统版的，网上找不到
