blockmesh生成网格总报错没有相邻面

blockmesh生成网格总报错没有相邻面，改来改去总有这个问题，还是不同的面报错，这是为什么呢？哭QvQ

@chapaofan 在 blockmesh生成网格总报错没有相邻面中说：

hex (14 11 12 13 29 30 31 32) (10 10 1) simpleGrading (1 1 1) //3

上面的顺序错了。
可能是下面这个：
hex (14 11 12 13 32 29 30 31) (10 10 1) simpleGrading (1 1 1) //3

@xiezhuoyu 修改过后这样报错是为什么呢？我之前修改也会这样报错
--> FOAM FATAL ERROR:
Inconsistent number of faces between block pair 1 and 3

xiezhuoyu

@chapaofan

这里面有矛盾的设置。
每条边上的单元数改为10试试（下图），再慢慢调整。

chapaofan

@xiezhuoyu oh!非常感谢！我再慢慢调整一下

chapaofan

找到问题所在了。大家一定要从离原点最近的坐标开始定义block，要不然划分网格就会乱掉QvQ

李东岳

用blockMesh来画这个也是个狠人！

@xiezhuoyu 大神能debug出来更狠！

liurui

截图.png 我也遇到了这个问题，我是这样命名block的但还是不行。麻烦您看看

chapaofan

@liurui 面的编号要用右手定则指向计算域外侧，所以就比如第一个hex应该是（0 7 6 1 8 9 14 15）
