Hi Bruno,
Thanks for your reply. I run snappyHexMesh in OpenFOAM2.1.0 on Tianhe1A, a supercomputer. So the memory shouldn't be a problem. OMG! I will redownload a OpenFOAM2.1.0 and try again, hope that it will work. Thank you again! Best wishes! Xiaowg Quote:

Hi, as I'm experiencing the same error (Parallel run: boundary condition missing on processorX/0) is there any way to set up a case from scratch in such a way that this error here is avoided without the need to run changeDict?
Thank you!

Hello OF experts and users,
please assist me in struggling the following problem: during run of icoFoam i included my utility: Code:
.... runTime.write(); #include "utility.H"; Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s" << " ClockTime = " << runTime.elapsedClockTime() << " s" << nl << endl; ...... Code:

Hello, Bruno
unfortunately command "PInfo" give a compilation error as "PInfo was not declared in this scope ". But the problem is not only at the screen output, but also i do not know how to order the code to analyze whole mesh that is spread to many processors (as is working with single run). And i need the results to be collected and to be written in the log file. Like this command in single run Code:
OFstream k(runTime.path()/"k.dat"); .... k<<"velocity "<<U[ii]<<endl; Regards Lev

Hi Lev,
Sorry about that. Apparently PInfo doesn't exist. But I vaguely remember reading about it... weird OK, by the description of what you're trying to do, it looks like to me that the probe or sampling utilities and/or function objects would be more suitable for what you want to do. And then there is also "swak4Foam": http://openfoamwiki.net/index.php/Contrib/swak4Foam Other than this... try searching this forum for more answers... I know they're in here somewhere... Best regards, Bruno

Hi all,
I'm following up with the issue that decomposePar does not preserve some boundaries and later on the solver complains about missing boundary definitions. Furthermore potentialFoam complains about the processorboundaries. My question is: Apart from the workarounds that have been constructed in the meanwhile to solve this: is there a outofboxsolution for OpenFOAM 2.1.1 that I am using out of box on ubuntu??? my script looks like this (without reconstructing) Code:
#!/bin/sh # Source tutorial run functions . $WM_PROJECT_DIR/bin/tools/RunFunctions cp r 0.org 0 > /dev/null 2>&1 runApplication blockMesh cp system/decomposeParDict.simple system/decomposeParDict runApplication decomposePar runParallel snappyHexMesh 2 overwrite parallel find . type f iname "*level*" exec rm {} \; ls d processor*  xargs i cp r 0.org/* ./{}/0/ $1 runParallel potentialFoam 2 initialiseUBCs noFunctionObjects writep runParallel `getApplication` 2 Thanks very much!! Marco

Hi dear FOAMuser
I have 3 machin include 12 core. I used scotch method for 12 processor, its ok on 1 machine. but when I used 2 or 3 machine for more processor, it dosent work without any error or warning.

Hi dear Bruno
Thank you for your reply actually i dont know how the OpenFOAM installed, This system with OpenFOAM has been gave me. I use OpenFOAM2.3.1. I reproduce the problem with motor bike and have a same problem with scotch method. when I using simple method ( for decompose) for cavity case, its work with 36 processor but didnt work with scotch method. I try to run simple method for my 3D asymmetric diffuser but similar to scotch method it didnt work. my command for run is: mpirun np 36 $HOME/OpenFOAM/OpenFOAM2.3.1/foamExec pimpleFoam parallel Thanks Marzieh
