Hi all,

I am having a problem with a bit of code in parallel. When I run it serially, there are no warnings but when I run it in parallel I get warnings. It doesn't stop my case from running, but it creates massive log files when I'm running across a few processors. If anybody has any idea as to the source of this warning and how to rectify it I'd appreciate it.

Please find below my piece of code and then a piece of the log file showing the warnings.

Code:
Info<< "Time: " << runTime.timeName()
<< "\nI am in the updateTractions file" << endl;





tractionDisplacementIncrementFvPatchVectorField& loadingPatchDU3 =
refCast<tractionDisplacementIncrementFvPatchVector Field>
(
DU.boundaryField()[loadingPatchID3]
);
tractionDisplacementIncrementFvPatchVectorField& loadingPatchDU2 =
refCast<tractionDisplacementIncrementFvPatchVector Field>
(
DU.boundaryField()[loadingPatchID2]
);

Info<< "loadingPatchDU3(a.k.a. traction3).DTraction Before= " << loadingPatchDU3.DTraction() << endl;
Info<< "loadingPatchDU2(a.k.a. traction2).DTraction Before= " << loadingPatchDU2.DTraction() << endl;



Snippet of log file:

I am in the updateTractions file
[3] --> FOAM Warning :

[3] in file /gpfs/mech/OpenFOAM/OpenFOAM-1.4.1-dev/src/OpenFOAM/lnInclude/FieldFunctions.C at line 322

loadingPatchDU2(a.k.a. traction2).DTraction Before= 94{(0 1000 0)}


Thanks in advance,
Michael
