APPLICATION TERMINATED WITH THE EXIT STRING: Floating point exception (signal 8)

其实这个问题发现好久了，做一下笔记：
自己在超算上运行OpenFOAM中solver时候会碰见这种错误：
APPLICATION TERMINATED WITH THE EXIT STRING: Floating point exception (signal 8)
发现解决办法就是自己重新写一个Makefile编译一下；
具体做法为：将Make/options中项添加到Makefile的CINCLUDES和CLDFLAGS中；将文件中的snappyHexMesh替换为你需要编译的文件。
具体原因可能是wmake和make所用的编译器版本不同导致的。

Makefile:
