Hallo, Everyone,

Today when I am running the pisoFoam today, I have this Error:

Case : /home/itvzl/OpenFOAM/gen_new/generators08052013/channel_st
nProcs : 1
sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
fileModificationChecking : Monitoring run-time modified files using timeStampMaster
allowSystemOperations : Disallowing user-supplied system call operations

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Create time

Create mesh for time = 0

Reading field p

Reading field U

pisoFoam: symbol lookup error: /home/itvzl/OpenFOAM/itvzl-2.1.x/platforms/linux64GccDPOpt/lib/libsyntheticTurbulencePoliMi.so: undefined symbol: _ZN4Foam20turbulentLengthScale3NewINS_12fvPatchFie ldINS_6VectorIdEEEEEEPS0_RKNS_10dictionaryERKNS_4T imeERKT_RKNS_4wordE

This libsyntheticTurbulencePoliMi.so library is not the openfoam selfcontained library. And I also have the library file libsyntheticTurbulencePoliMi.so in the user folder. But there is symbol look up error. Does anybody know what happened and how could I solve this problem?

Thank you very much

Best Regards

Litchy

And I tried today with another case, the same library needed in the controlDict. Also the same solver, it is still the same problem. Symbol look up error.Is this because of the library's problem? For example, not compiling it correctly?

And the same look up error? Do you think it's because the problem of the library or the way we compile it ?

Hi,

In my case I have found what the problem was. In the file make/files I did not include the correct *.C file. That means that the library is created but the *.C files are not linked correctly. Therefore, information is missing for the solver to run. May be in your case the file that contains

turbulentLengthScale3NewINS_12fvPatchFie

is not linkedcorrectly.

I hope this helps

Hey,
Thank you first for your hint.

And I check my file in the Make folder:

syntheticTurbulence=syntheticTurbulence

$(syntheticTurbulence)/syntheticTurbulence/syntheticTurbulence.C
$(syntheticTurbulence)/syntheticTurbulence/generateSyntheticFluctuations.C

$(syntheticTurbulence)/turbulentLengthScale/uniform/uniformLengthScale.C
$(syntheticTurbulence)/turbulentLengthScale/generic/genericLengthScale.C
$(syntheticTurbulence)/turbulentLengthScale/kw/kwLengthScale.C
$(syntheticTurbulence)/turbulentLengthScale/turbulentLengthScale/turbulentLengthScale.C

$(syntheticTurbulence)/syntheticTurbulenceInletFvPatchField/syntheticTurbulenceInletFvPatchField.C

LIB = $(FOAM_USER_LIBBIN)/libsyntheticTurbulencePoliMi



It seems to be fine.

But there is one thing, every *.C file should be accompanied by a *.H file with the same name, right? I just found one *.C file with a *.H file in a different name in the 'syntheticTurbulence' folder. I don't know if this is the problem. I'll try on it.

Best Regards

Hi. I finally got the simulation working but i have a litlle problems with definition of delta T and courant number which sometimes send back an error during the process. Could you help me with this doubt? What possibly Im doing wrong?

Another question is that Im doing a 3D simulation but i can only see Ux and Uz during the calculation. Is that normal?

Please, somebody help me!!!


Regards

Maybe your courant number is larger than one in some fine mesh region? I could see Ux, Uy, Uz, in my simulation. I'm also a beginner of this. Hope others could help you.

Good luck.
