| Summary | 0002644: Particle tracking cannot be run in parallel for the cases with AMI patches. | ||||
| Description | Particle tracking cannot be run in parallel for the cases with AMI patches. It says: "Particle tracking across AMI patches is only currently supported for cases where the AMI patches reside on a single processor." But the decomposition of AMI patches on one processor through the "singleProcessorFaceSets" function in decomposeParDict leads to the same error! Constructing kinematicCloud kinematicCloud [2] [3] [3] [3] --> FOAM FATAL ERROR: [3] Particle tracking across AMI patches is only currently supported for cases where the AMI patches reside on a single processor [3] [3] From function void Foam::Cloud<ParticleType>::checkPatches() const [with ParticleType = Foam::CollidingParcel<Foam::KinematicParcel<Foam::particle> >] [3] in file /home/armin/OpenFOAM/OpenFOAM-dev/src/lagrangian/basic/lnInclude/Cloud.C at line 59.

Could you please upload the case that reproduces the error? |

Hi Will, yes, it's already there. |
|
|
It's not the same error on decomposePar. Your "singleProcessorFaceSets" setting is referencing a face-set that doesn't exist. There is a bug that generates a hang in this case, to do with initialisation of the TrackData::switchProcessor flag. I will fix it, but it is not the issue described here, so it would be misleading to associate that fix with resolution if this report. |
|
|
Thanks Will. Yes, the "singleProcessorFaceSets" setting in the decomposeParDict of this case refers to another case with the faceSet "AMI", where it leads to the same error. I can send that case too in order to show, that this setting doesn't solve the problem. But it's not the main problem. I've already sent a simple case just to show the main problem: Particle tracking cannot be run in parallel for the cases with AMI patches. |

It does work if you create an AMI face set and the appropriate singleProcessorFaceSets entry in the decomposeParDict. It's running on my machine right now. You have not demonstrated that there is a bug anywhere. The fact that the AMI patches must reside on the same process is a limitation, sure, but the error message explains this. |
|
|
Okay, since I cannot upload more here, I will send another report with a case with "singleProcessorFaceSets" setting, which leads to the same error. And about this limitation, that particle tracking cannot be run in parallel for the cases with AMI patches, I've read in the bug report 0002081, that "a workaround has been provided which can overcome the issue and a more user-friendly solution requires funding at this stage.". Therefore I'm eagerly waiting for the new workaround. It would be very interesting for me. |

After writing of the last note the upload part is enabled again. Therefore I've uploaded the second case (rotatingDisc) here as well. As you can see, the AMI faceSet resides now only on the processor 5. But the particle tracking (log.icoUncoupledKinematicParcelDyMFoam) gives the same error. |
|
|
There's no bug. This is a user support request. |
|
|
Thank you for your hints, Will. I found the solution. Regards, Armin |
