Are you running 5.0 or 5.x? You refer to both in your report: Product Version 5.0 I installed version of Ubuntu 16.04 LTS, then I installed OpenFoam 5.x 3. Operate on OpenFoam 5.0 If you are running 5.x could you let us know how recent? |

Yes, I am sorry for the confusion. I am running with Openfoam 5.x Build : 5.x-197d9d3bf20a, i hope this is a way to show you the version. Anyway I downloaded this version from the website around three weeks ago. Thank you for the support, Raffaele |

I have setup the case to run in OpenFOAM-5.x and OpenFOAM-dev and both are running fine and already well beyond the point that your run crashes. Have you tried reducing the maximum Courant number? The case may be a bit fragile at such large Courant numbers and may run fine on your system if you reduce it. |
|
|
No I didn't try, shall I change in the controlDict from 25 to 20 or even more ? It need for me a couple of hours to run until my crash so I will update you in the afternoon :) Thanks a lot |

Hello henry, I defined 20 as max value of the Courant number but still crash, should I continue to lower the value? |
|
|
I am unable to reproduce the problem, on my machine the case runs fine in OpenFOAM-5.x and OpenFOAM-dev. |
|
|
Yes, you are right, anyway I will try to test without virtual machine. thanks a lot for the support. |
