OF继续计算时报错

冠竹

开学后将原本在家里跑得模拟关掉后打算回学校继续进行，结果发现在将controlDict文件中改为latestTime后再进行

mpirun -np 6 simpleFoam -parallel

时，of直接报错，这个问题应该怎么修改呢？
报错代码如下所示：

这种玄学问题，一般重启能解决。如果不能重启，重新登录、重新加载of环境之类的。

或者试试，不要用latestTime。直接写最后的那个时间节点，就是latestTime对应的文件夹名

李东岳

@冠竹在 OF继续计算时报错中说：

在家里跑得模拟关掉后

估计是latestTime的结果写了一半，就关掉了。导致数据不全。我有时候遇到过。按照 @bestucan 说的方法可以试一试

冠竹

@bestucan 您好，我尝试了重启电脑，重新加载OF环境，将controlDict中latestTime改成了startTime,

application     simpleFoam;

startFrom       startTime;

startTime       3700;

stopAt          endTime;

endTime         40000;

deltaT          1;

writeControl    timeStep;

writeInterval   100;

purgeWrite      0;

writeFormat     ascii;

writePrecision  6;

writeCompression off;

timeFormat      general;

timePrecision   6;

runTimeModifiable true;

functions
{
    #includeFunc streamlines
}
functions

{

#includeFunc            residuals

}

但是这个问题还是存在，而且更玄学的是，我尝试用其他算例进行并行计算时也出现了同样的报错，似乎我无法使用OF去进行并行计算了
很抱歉这样打扰您，但还是希望您能不吝赐教，感激不尽

BlookCFD

用学校的电脑重头开始算，然后续算看看。

bestucan

@冠竹哦，对了，用的是多线程，那么，最保险的做法是，重新加载环境，重新decompose。
如果是换机器了。先把各个process组成一个时间文件，再重新decompose。

如果是of自带的并行算例AllRun也报错。
那应该是系统更新，导致当初编译of依赖的系统库变了。

最后的方法就是重新编译of了

@bestucan 我去试试，感谢大佬:
