openfoam从9还是10开始，编译需要超大内存。那次大版本更新一堆编译爆了的。要么增加内存条或者swap，要么编译的时候不要直接 -j 用上所有的核，用少一些核，内存占用会降低，只是编译速度慢点。

可以编译的时候开着系统资源管理器看着内存占用，是不是到100%之后猛的下降。

确定是“自动关机”而不是“自动重启”？如果只是自动重启，兴许只是内存满了，把GUI撑爆了，GUI自动重启了。

如果确定是自动关机的故障就别开机了。自动关机的时候估计哪里电流过载之类的，多冲几次就成永久故障了。

@Afr1yne 可以的。可以参考溃坝算例里设定水的区域和含水量

@世界函数画网格的时候、计算的时候都可以修改。在fluent里，网格那一栏。有检查网格质量、防缩网格尺寸，也有整体移动网格的。把网格的一个边界点对到原点上就行了。

OpenFOAM里有个setFields，就像fluent里的path。

这些是内部函数，只有头文件里有声明。是常见的商业软件保密方法。（只发布头文件和源代码编译成的动态链接库）

如果要使用，

第一步，包含定义该函数的头文件
第二步，编译的时候链接到包含该函数定义的动态链接库。

可以使用grep找到包含该函数的声明头文件和各状况下的动态链接库。

搜你的版本的ansys的这个文件，里面有解释和使用范例

极限分析法：攻角90度。

然后就成了圆柱绕流了，有卡门涡街了。来回摆的涡，即使没有湍流，也不会收敛了。

你是用稳态算的吧，可以用瞬态试试，周期波动稳定后，选一些连续的波动周期做个时均场，试试能不能得到气动参数
