问题描述
大家下午好， 我正在尝试使用 simpleFoam 计算平板状主体周围的流动情况，由于代码过时，我必须更改该情况的某些部分，以便它们可以使用最新版本的 Foam 语法。刚刚出现了一个异常错误，在网上也找不到类似的案例，如果是一个愚蠢的问题，我很抱歉：
--> FOAM Fatal error: (openfoam-2012)

收到这条消息后终端冻结了，所以我不得不使用 ctrl+c 来终止进程。以防万一，我尝试将速度文件 /0/U 中的尺寸从 [0 1 -1 0 0 0 0] 更改为 [0 1 -2 0 0 0 0]，但是，正如预期的那样，它只是给了我另一个错误：
--> FOAM Fatal error: (openfoam-2012)
