Dear Foamers,
I am developing a solver. It runs OK as a serial job. I need to run it in parallel. I cannot apply decomposePar! I get this error for the last processor (regardless of number of processors). I have nothing in the code nor the input files that wants this "time-series" thing!!! I tried the decomposeParDict with a tutorial and it runs. Any ideas are appreciated! Error: Code:
Constructing processor meshes Processor 0 Number of cells = 22542 Number of faces shared with processor 1 = 109 Number of processor patches = 1 Number of processor faces = 109 Number of boundary faces = 45409 Processor 1 Number of cells = 22542 Number of faces shared with processor 0 = 109 Number of faces shared with processor 2 = 95 Number of processor patches = 2 Number of processor faces = 204 Number of boundary faces = 45332 Processor 2 Number of cells = 22542 Number of faces shared with processor 1 = 95 Number of faces shared with processor 3 = 97 Number of processor patches = 2 Number of processor faces = 192 Number of boundary faces = 45334 Processor 3 Number of cells = 22542 Number of faces shared with processor 2 = 97 Number of processor patches = 1 Number of processor faces = 97 Number of boundary faces = 45407 Number of processor faces = 301 Max number of cells = 22542 (0% above average 22542) Max number of processor patches = 2 (33.3333% above average 1.5) Max number of faces between processors = 204 (35.5482% above average 150.5) --> FOAM FATAL IO ERROR: file "/home/hisham/OpenFOAM/numubuntu-2.0.0/waveTankFoam/fineTutorial_waveTankFoam/time-series" does not exist file: /home/hisham/OpenFOAM/numubuntu-2.0.0/waveTankFoam/fineTutorial_waveTankFoam/time-series at line 1.

Greetings Hisham,
Mmm, that's an odd error message... My guess is that you don't have any time instance folder, such as "0". I can't test this right now, so may I ask you to post the tree list of your case folder: Code:
tree -s Bruno

Hi Hisham,
You have many files that shouldn't be where they are. Allow me to explain:
You wouldn't leave a screw driver on the ground of a wind tunnel experiment and then turn on the fans, would you? Best regards, Bruno

Hi Bruno,
As you've expected. It is the boundaryData that causes the problem. I do not need the timeVaryingMapped BC for now, so I guess your advice for keeping things tidy pays off. I removed the boundaryData altogether and it decomposes now fine. Thanks Hisham |

hey, i did this mesh in salome and ideasToUnv worked fine but after that when i decomposed it i had this error
Constructing processor meshes #0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam201/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigSegv::sigHandler(int) in "/opt/openfoam201/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 in "/lib/x86_64-linux-gnu/libc.so.6" #3 in "/opt/openfoam201/platforms/linux64GccDPOpt/bin/decomposePar" #4 in "/opt/openfoam201/platforms/linux64GccDPOpt/bin/decomposePar" #5 in "/opt/openfoam201/platforms/linux64GccDPOpt/bin/decomposePar" #6 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #7 in "/opt/openfoam201/platforms/linux64GccDPOpt/bin/decomposePar" Segmentation fault i have had no errors so far with my decomposePar ever... please help me I'm just stuck |

Greetings Alhasan,
Did you check the mesh? Code:

there was a problem with the mesh...!!!! sorry for the inconvinence... thanks ...
the problem was the there was one extra face on just one wall..!!!! and it couldn't segment the number of cells equally i guess...!!! thanks. |
