undefined symbol Error After Modifying Turbulence Model

NorthCFD · November 9, 2023, 07:58

Hello,

I was learning to modify and compile turbulence models from a youtube (can't post link) tutorial. It is trying modify kOmega model

My options file inside Make directory is as

Code:

EXE_INC = \
    -I$(LIB_SRC)/TurbulenceModels/turbulenceModels/lnInclude \
    -I$(LIB_SRC)/TurbulenceModels/incompressible/lnInclude \
    -I$(LIB_SRC)/transportModels \
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude

LIB_LIBS = \
    -lincompressibleTransportModels \
    -lturbulenceModels \
    -lfiniteVolume \
    -lmeshTools

Whole setup is same with tutorial but after compilation, when I try to run a case with new library (calling it in controldict). I get this error. When I try to grep this _ZNK thing, I got nothing.

Code:

--> FOAM Warning :
    From void* Foam::dlLibraryTable::openLibrary(const Foam::fileName&, bool)
    in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 65
    Could not load "$FOAM_USER_LIBBIN/myturbulentTransportModels.so"
/home/myname/OpenFOAM/myname-v2006/platforms/linux64GccDPInt32Opt/lib/myturbulentTransportModels.so: undefined symbol: _ZNK4Foam29incompressibleTurbulenceModel2muEl

I am using OpenFOAM v2006 at a cluster.

My first consideration was some local file issue with cluster but I don't know.

I can supply other materials.
Please help, thank you.

Somewhat it is solved. I can see the name of my turbulence model. But now some other thing is broken.

As a last resort I copied libraries I need to the user lib directory. Then after compilation and running simpleFoam it started giving me duplicate entry errors. Then I deleted those libraries from user lib and compiled again but error didn't disappear. I don't know whether I broke something by doing this.

Error is:

Code:

Hi Kuzey,

I have met the "duplicate entry in runtime selection table" warning before, and I think that's because I have two versions of source code of my custom class, and during the compilation, different parts of OpenFOAM used different versions. So, my custom class register with the runtime selection table twice.

From my personal experience, I didn't find that it will effect the functionality of the solver (except from raising this warning).

Hope this would help,
Yueyun

Thanks for the answer Yueyun.

Can you describe more about "I have two versions of source code".

And while solver works and goes few hundred iterations, it crashes before finishing.

Thanks,
Kuzey.

simpleFoam starts with above error, works normally and can solve turbulence. But at the end it gives this.

Another error occurs when working with a third-party solver which is density based compressible. Using the very same turbulence model, it gives this error at the start:

Code:

Create time

--> FOAM Warning :
    From void* Foam::dlLibraryTable::openLibrary(const Foam::fileName&, bool)
    in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 65
    Could not load "$FOAM_USER_LIBBIN/myturbulentTransportModels.so"
/home/myname/OpenFOAM/myname-v2006/platforms/linux64GccDPInt32Opt/lib/myturbulentTransportModels.so: undefined symbol: _ZTIN4Foam29incompressibleTurbulenceModelE
Create mesh for time = 0

Those are really weird, while I can understand an error with third-party solver. I don't understand the reason with other, I did what tutorials exactly did. Maybe because of cluster?

Thanks for any help

November 9, 2023, 07:58	undefined symbol Error After Modifying Turbulence Model	#1
NorthCFD New Member Kuzey Can Derman Join Date: Oct 2022 Posts: 12 Rep Power: 4	Hello, I was learning to modify and compile turbulence models from a youtube (can't post link) tutorial. It is trying modify kOmega model My options file inside Make directory is as Code: EXE_INC = \ -I$(LIB_SRC)/TurbulenceModels/turbulenceModels/lnInclude \ -I$(LIB_SRC)/TurbulenceModels/incompressible/lnInclude \ -I$(LIB_SRC)/transportModels \ -I$(LIB_SRC)/finiteVolume/lnInclude \ -I$(LIB_SRC)/meshTools/lnInclude LIB_LIBS = \ -lincompressibleTransportModels \ -lturbulenceModels \ -lfiniteVolume \ -lmeshTools Whole setup is same with tutorial but after compilation, when I try to run a case with new library (calling it in controldict). I get this error. When I try to grep this _ZNK thing, I got nothing. Code: --> FOAM Warning : From void* Foam::dlLibraryTable::openLibrary(const Foam::fileName&, bool) in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 65 Could not load "$FOAM_USER_LIBBIN/myturbulentTransportModels.so" /home/myname/OpenFOAM/myname-v2006/platforms/linux64GccDPInt32Opt/lib/myturbulentTransportModels.so: undefined symbol: _ZNK4Foam29incompressibleTurbulenceModel2muEl I am using OpenFOAM v2006 at a cluster. My first consideration was some local file issue with cluster but I don't know. I can supply other materials. Please help, thank you.

yueyun New Member Yueyun Xi Join Date: Nov 2022 Posts: 14 Rep Power: 4	Hi Kuzey, I have met the "duplicate entry in runtime selection table" warning before, and I think that's because I have two versions of source code of my custom class, and during the compilation, different parts of OpenFOAM used different versions. So, my custom class register with the runtime selection table twice. From my personal experience, I didn't find that it will effect the functionality of the solver (except from raising this warning). Hope this would help, Yueyun Last edited by yueyun; November 13, 2023 at 08:57. Reason: Fix typo

NorthCFD New Member Kuzey Can Derman Join Date: Oct 2022 Posts: 12 Rep Power: 4	Thanks for the answer Yueyun. Can you describe more about "I have two versions of source code". And while solver works and goes few hundred iterations, it crashes before finishing. Thanks, Kuzey.
