Hi,

I have been working with OpenFoam for the last few months. Now I wanted to continue working from home ( Home quarantined ) . I am accessing a workstation via Remote desktop connection from my laptop.

A parallel running of a dambreak case on 16 processors gives the following error:
"
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[27991,1],0]
Exit code: 145 "
Any help please!

Note that: a) similar cases were working fine when I was working in my office.
b) The same case is working fine in my laptop
c) The same case with a single processor is ok in the workstation
d) I am connected via VPN to the company's internet to access the workstation.

I ran:
decomposePar

then:
mpirun -np 3 interMixingFoam -parallel


And then I have got the same error:

Kindly someone help me with this issue.

I found the error. My computer's username has a space in it so that was the problem.
Unfortunately, the username can not be changed...

Looks like a windows mapping issue. The easy solution, which normally works fine, is to enable spaces.

In the etc/controlDict

InfoSwitches
{
    // The default ASCII write precision
    writePrecision  6;

...


    // Allow space character in fileName (use with caution)
    // Ignored (always 1) for Windows.
// Default:    allowSpaceInFileName    0;


    allowSpaceInFileName    1;
}

This will likely get it working for you.

Hello Geb1313,

Were you able to find a solution? My case is very similar. I am running the program in parallel and remotely with Chrome Remote Desktop. The error appears after several iterations.

Per user-direction, the job has been aborted. ------------------------------------------------------- -------------------------------------------------------------------------- mpirun detected that one or more processes exited with non-zero status, thus causing the job to be terminated.

[sharkilwo5]

try to add a hostfile in the case folder and run the case as shown below

mpirun -np 4 --hostfile hostfile interMixingFoam -parallel

[saavedra00]

Thanks for your suggestion Sharkilwo5. I am running in parallel but locally in a multiprocessor machine.

The problem was related to the stability. The case is constrained by the timestep.

Hi,

I have the same problem now. Could you please explain that what do you mean it is constrained by the timestep?

Cheers

Hi Basma,
Can you explain what error exactly you are getting? I will try to help you.

Hi There


I am running a snappyHexMesh job on remote machine nodes and I have some similar error that shows up. The machines are at the university server remote machines so I cannot touch the installation.

Right now for the sake of trying out I am using the STL files from “turbine siting” and increasing the refinement level. Since I use the original tutorial file I know there is no problem with that one. After a refinement level ( in my case it is 5) I get a similar error like the posters previously.

My decomposition is hierarchical (4 7 1)

(Previous Stuff).....
Shell refinement iteration 2
----------------------------

Marked for refinement due to distance to explicit features : 0 cells.
Marked for refinement due to refinement shells : 2372394 cells.
Marked for refinement due to refinement shells : 2372394 cells.
--------------------------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpirun noticed that process rank 25 with PID 7837 on node a013 exited on signal 9 (Killed).

I am using 28 cores but this stuff happens in even 168 cores.I don’t think computational power is the issue (My size is barely 2 million or so).The command I use is.

mpirun -np 28 snappyHexMesh -overwrite -case “......./.../TurbineSitingDryRun_19042023/"

I am using openfoam-v2212 but have been experiencing the same problem with openfoam-v1812 so I don’t think it’s a library issue or installation issue.

I believe somehow the system is unintentionally caping some computational power which means it’s crashing one note and exiting.

Can anyone offer any suggestions at this point? I appreciate all the help. Remember I cannot change that much on the installation so I have to do something on my end
