@五好青年 http://www.jhydrodynamics.com/en/download-of-liutex-code/
是这个代码么？我对liutex的计算方法不熟悉。但肯定是代码里面什么地方某个算法卡住了。

这种期刊的代码可以直接找通讯作者交流类似的技术问题。

https://www.cfd-china.com/topic/3499 在这里面有一个
获取某个函数的计算时间，你可以放在代码里面看看哪里的计算时间比较长，卡在哪里了。

目前我将cavity算例改成三维，三个方向网格相同，试算了后进行Liutex后处理。记录如下：
30^3网格 单核，Liutex处理时间：4s
35^3网格 单核，Liutex处理时间：14s
40^3网格 单核，Liutex处理时间：60s
45^3网格 单核，单核，Liutex处理时间：131s
50^3网格 Liutex处理时间：327s
55^3网格 单核，浮点溢出
58^3网格 单核，浮点溢出
60^3网格 单核，浮点溢出
70^3网格 单核，浮点溢出
80^3网格 4核并行后处理，报错300万网格以前的算例，扩大机器内存，单核处理3天了，还没出结果

#include <chrono> auto start = std::chrono::steady_clock::now(); // Functions here auto end = std::chrono::steady_clock::now(); auto diff = end - start; Info<< "Calculation using " << std::chrono::duration <double, std::milli> (diff).count() << " ms" << endl;你可以用上段代码测试哪个函数运行时间比较长

@yhdthu
您好
我尝试往OF官网版本上移植，提示了一些报错，主要有：error: ‘complex’ was not declared in this scope
经过很久的折腾，发现您可能参考tensor.C文件来修改的，并且我对比了OpenFOAM低版本的tensor.C来逐个修改报错，但是始终没能解决。
可否帮忙帮忙编一个低版本的，或者给一些修改的思路
