Hi everyone,

I need to make some subtle changes to icoUncoupledKinematicParcelFoam, for a particular application I have. After making them and compiling (whitout any problem, I believe) I tried running the case and got the following message,

symbol lookup error: /opt/openfoam6/platforms/linux64GccDPInt32Opt/lib/liblagrangianTurbulence.so: undefined symbol: _ZN4Foam13ParticleForceINS_14KinematicCloudINS_5CloudINS_12ThermoParcelINS_15KinematicParcelINS_8particleEEEEEEEEEE8typeNameE

I couldn't figure out where my mistake was, so I tried running the tutorial case (hopper) for the original icoUncoupledKinematicParcelFoam. And I got the exact same message.

I'm not sure if there is some problem with my installation or what, but any help is welcome

Hi Eduardo,


1) Have you worked on the original source code or created a separate copy in your user directory? (please create a copy)



2) Have you modified both the library in src/lagrangian/ and this solver or only the solver? If this is at solver level, we'll need more info.



3) Have you given the solver another name so that you can still run the original solver on the tutorial case?


Cheers,
Vincent

Hi Vincent,

thanks for the reply

1)
All changes were made inside $WM_PROJECT_USER_DIR and not in the original source code.

2)
The library was not changed.

3)
Yes, they have different names.

Hi Eduardo,

OK, then I understand this sentence better now:

4) Have you tried rerunning

./Allwmake > log 2>&1 &

in src/?
5) Are other solvers working properly (e.g., icoFoam using the incompressible cavity case)?

Vincent

Hi Vincent,

4)
I'll do that and tell you what happens.

5)
The only solvers not working are the lagrangian ones, all wielding the same error message.

To test if the problem was with the library, I created a copy of icoUncoupledKinematicParcelFoam and the only modification I made (besides the name and the directories, where appropriate) was to remove the line "-llagrangianTurbulence " in the Make/options file. Doing that, the solver works just fine, without the turbulent properties, of course.
