| Summary | 0002776: 'wallHeatFlux' function object does not work in parallel due to issue with "coupledFvPatchField::snGrad" | ||||
| Description | Following up on what I commented in report #2722, I've now got more details on the issue regarding the tutorial case "chtMultiRegionSimpleFoam/multiRegionHeaterRadiation" and using the function object 'wallHeatFlux': - If the script 'Allrun' is used, everything works just fine. - If the script 'Allrun-parallel' is used, it crashes with the following message on all processes (only showing for the master here): [0] --> FOAM FATAL ERROR: [0] Not implemented [0] [0] From function Foam::tmp<Foam::Field<Type> > Foam::coupledFvPatchField<Type>::snGrad() const [with Type = double] [0] in file lnInclude/coupledFvPatchField.H at line 151. [...] [0] #2 Foam::coupledFvPatchField<double>::snGrad() const [0] #3 Foam::functionObjects::wallHeatFlux::calcHeatFlux[...] I've confirmed that this only happens with OpenFOAM-dev (latest Deb, dev-17954fc1734a), since OpenFOAM-5.x (latest Deb, 5.x-197d9d3bf20a) works just fine. | ||||
| Steps To Reproduce | Append the following to 'system/controlDict': functions { #includeFunc wallHeatFlux(region=heater) //#includeFunc wallHeatFlux(region=bottomAir) //#includeFunc wallHeatFlux(region=topAir) //#includeFunc wallHeatFlux(region=leftSolid) //#includeFunc wallHeatFlux(region=rightSolid) } (Left commented out the other entries, so that it's easier to uncomment and re-check once the issue is fixed.) Then run the script: ./Allrun-parallel Wait a few seconds, the solver crashes at time step 300 (at write time), then check the file 'log.chtMultiRegionSimpleFoam' to see the complete stack trace. | ||||
| Additional Information | Given the error message and the indication that one version works and the other doesn't, is the reason why I suspect that this is due to the optimization that was done for #2725: https://bugs.openfoam.org/view.php?id=2725 However, I suspected that this issue was related to the region-coupled boundaries, but instead it's related to the processor boundaries... or at least so it seems, since I haven't investigated any further than this. | ||||
