用ICEM CFD划分网格遇到的问题，请指教

在ICEM CFD中划分网格遇到的问题
1.A minor internal error has occurred.
You may continue to work but if problems arise they may be related to this error.
Try using the check/fix function to fix the problem
The following message was designed to aid developers fix the problem:

internal error in edge_node_dim: none touching

Mesh size:
        nodes = 27073000
        quads = 4227238
        hexas = 25574748
  

2.internal error in edge_node_dim: none touching

导入Fluent后出现的问题
The mesh contains 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.

请各位高人不吝赐教，在此谢过了。

ICEM做六面体网格出现了这种提示，一般是block出了问题，fluent读不了这种网格。

可是block会出什么问题？对网格划分有影响吗？会对导入Fluent计算有影响吗？

我也不知道具体是哪里的问题，我曾经也碰到过这样的问题。
一般对ICEM的block进行切割删减不会出现这样的问题，但是如果有复制block，extrude block，或者利用点生成block，有时候会出现这个问题。

check的时候，我也老遇到这个
“The mesh contains high aspect ratio hexahedral

”不知如何是好

我只对block进行切割和删除，没有进行过其他的操作，但就是出现了上述问题，真不知该怎么办。另外，我在分割block过程中，经常会另存为，但每次都出现 error copying block      no such file or directary

楼主的问题解决了吗？我也遇到了。怎么处理啊？

可能是几何精度不够，在划分过密网格的时候映射会出现问题
