| Summary | 0003879: Problem using LoadBalancer with cyclic BC | ||||
| Description | Hello, I ran into a problem running LoadBalancer with cyclic BC. After the run, running reconstructParMesh and then reconstructPar leads to the following error: Create time Reconstructing fields for mesh region0 Time = 1e-05s Reconstructing FV fields Reconstructing volScalarFields OH CN C2H3 #0 Foam::error::printStack(Foam::Ostream&)corrupted double-linked list Aborted Also, an extra text appears in e.g. reconstructed CN file in the above example with processorBC? procBoundary0to3throughtop { type processor; patchType processorCyclic; value nonuniform List<scalar> 100 I am not sure if the laodBalancer handles the cyclic BCs correctly during the simulation in the first place. But also it seems there is an issue when the case is reconstructed. The OpenFOAM code is updated to the latest commit (regarding AMI BC). Regards. | ||||
| Steps To Reproduce | - cd OpenFOAM-10/tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D_GRI - blockMeshDict: divide the outlet bc into two cyclic patches (e.g. top and bottom) - 0.orig: update the boundary conditions - controlDIct: set endTime 4e-5 - ./Allrun-parallel | ||||
| Additional Information | I attached the modified tutorial. | ||||

What level of funding could you allocate to further work on dynamic load-balancing to resolve this issue? |

Version 10 does not support the reconstruction of meshes with processor cyclic patches. Dev does support this. It was added in the following commit: https://github.com/OpenFOAM/OpenFOAM-dev/commit/7e2dd6dd So, you will need to upgrade to dev if you wish to use this feature. Also, in investigating your case, I found a further bug in the handling of redistribution of processor cyclic fields. This has been fixed here: https://github.com/OpenFOAM/OpenFOAM-dev/commit/46107572 So, if you upgrade to dev, make sure that it is a recent enough pull to include this commit. Otherwise you will just hit another bug. |
