Hi everyone!
I'm trying to run the rhoSimpleFoam/gasMixing/injectorPipe tutotial's case with little lucky. After solving the case, I haven't been able to see the results. If I use the command "reconstructPar", the next error appears: Code:
--> FOAM FATAL ERROR: (openfoam-2012) cannot find file "/media/sf_OpenFoam/run/tutorials/compressible/rhoSimpleFoam/gasMixing/injectorPipe/processor0/constant/polyMesh/pointProcAddressing" From virtual Foam::autoPtr<Foam::ISstream> Foam::fileOperations::uncollatedFileOperation::readStream(Foam::regIOobject&, const Foam::fileName&, const Foam::word&, bool) const in file global/fileOperations/uncollatedFileOperation/uncollatedFileOperation.C at line 547.

Hello Rebeca,
It seems like you have a processor*/constant/polyMesh folder structure. reconstructParMesh works when there is only polyMesh folder under each processor* folder. Once all the mesh is reconstructed then you can use the reconstructPar to get all the variable data in single file/time slot. Also sometimes paraview crashes when loading this type of data. You can use foamToVTK to convert this data since each time folder might have a different mesh due to DyM refinement or topology changes. Hope it works for you. |

For me, I have got this error:
Create time Reconstructing fields region=region0 --> FOAM FATAL ERROR: (openfoam-2206) cannot find file "/home//tsl/scratch/agile_flight/OpenFOAM/model_black_UAV_2.5e-5_5.59M_6dof_moi1_SST/processor0/2e-05/polyMesh/pointProcAddressing" From virtual Foam::autoPtr<Foam::ISstream> Foam::fileOperations::uncollatedFileOperation::rea dStream(Foam::regIOobject&, const Foam::fileName&, const Foam::word&, bool) const in file global/fileOperations/uncollatedFileOperation/uncollatedFileOperation.C at line 540. FOAM exiting Hence, I wrote a "of_copy_ProcAddressing_loop.sh" script: Code:
#!/bin/bash for ((i = 0; i < $1; i++ )); do echo "$i" cp processor$i/constant/polyMesh/*ProcAddressing processor$i/$2/polyMesh/ done of_copy_ProcAddressing_loop.sh a b where: a = no of processors b = time saved e.g. of_copy_ProcAddressing_loop.sh a b 512 0.1 Hope it helps. |

Hi quarkz,
Iam have a same issue in case of AMI and Openfoam2306 and 2212. I tried your scipt it does not work for me properly. syntax : sh of_copyProcAddressing_loop.sh 128 0.05 Error is bad for loop variables? Do you have ideas to fix reconstructPar error? Thanks, Zsolt |

Hi dragazsolt, there's no need for sh in front, just run it like:
./of_copy.sh 512 0.1 if the file is in the same dir. hope it works. |

1. create a .foam file using touch command ex. touch case.foam
2.open case.foam using paraview 3.in paraview properties - case type change it to decomposed case. thank you |

you have to run:
Code:
