CFDEM error message: Trying to use the dummy Pstream library.

Submitted by moritzhoefert on Thu, 07/14/2011 - 11:01

Hi there,

I installed CFDEM based on OF 1.7.x and liggghts 1.3.3. (Remark: other than issues with using consistent compilers and the -fPIC option and fiddling around with paths it went smooth) and try to run it on cfdemSolverPisoCase_shared/settlingTestMPI

The error occurs in the bash function parCFDDEMRun(). It executes decomposePar successfully, fails removing couplingFiles/* because there are none. The fatal error occurs during the execution of the solver. Please find the complete error message below.

What does that error mean? Where does it come from? Is a library built incompletely?

One more thing: In spite of getting the error message, an evince window pops up showing CFD/octave/cfdemSolverPiso_settlingTestMPI.eps

Thank you for any comments!
Regards,
Moritz

Hi!

This error is completely new to me.

please check if the installation really worked and if all environment vars in the /etc/bashrc are set correctly.

you dont have to use the scripts for running the case - which i would recommend until everything works fine -

use:
#- in case the Allrun.sh script does not work for you:
cd CFD
decomposePar
mpirun -np 2 cfdemSolverPiso_shared -parallel
reconstructPar
foamToVTK
cd ../DEM
pizza -f pizzaScriptInit
(quit with Strg-d)
visualize the data with paraview

Please keep me posted on your progress.

cheers,
Chris

Hi Chris,

thanks for your reply. During the wmake libso process of liblagrangianCFDEM_shared.so I get several messages of the kind

could not open file incompressible/turbulenceModel/turbulenceModel.H for source file subModels/voidFractionModel/centreVoidFraction/centreVoidFraction.C
Making dependency list for source file subModels/locateModel/locateModel/locateModel.C

but nevertheless the library is made. Maybe there is something wrong with my compilers and linkers.

Is there a way to figure out if the solver fails to load a function from a shared object? Any other comments?

Kind regards,

I got the same error when I recently had to rebuild the cfdem on a new machine. I went into the /src/Pstream folder inside OpenFOAM and just forced a ./Allwmake. The console told me it was already built but when I went back to the CFDEM everything worked. Possibly this was a fluke but I wanted to share my solution.
