It runs fine on my installation and converges in 10 iterations. Did you try cleaning up before recompiling after updating? https://openfoam.org/download/source/compiling-openfoam/ |

That case runs fine here: . . .

I recompiled the sources but the crash still occurs. It is what I did: cd /path/to/OpenFOAM-dev git pull wclean all wcleanPlatform ./Allwmake -j I use clang-6 compiler, if it important. I attached a compilation log. |
|
|
It looks like the clang optimizer is generating incorrect code, try lowering the optimization level or use gcc instead. |
|
|
Yea, there is no crash with gcc. |
|
|
This appears to be a bug in the clang-6 optimizer. |
