Hello,
What is the path of your MPI (Open MPI) install used with Code_Saturne ? Do you have multiple MPI installs ?
Best regards,

Hello,
the path of MPI:
CS_MPI_PATH=/usr/lib/openmpi/1.4-gcc/bin
2 installations of MPI, one with the installer of code_saturne 1.33 and another with code_saturne 2.0.1

Best regards,
Eric

Hello,

I suspect the MPI library loaded by Code_Saturne 2.0.1 is not the one with which it was compiled. This may happen if you have an LD_LIBRARY_PATH set for Code_Saturne 1.3, or if its version of OpenMPI is in system paths and 2.0’s is not.

You should try to

export LD_LIBRARY_PATH=/usr/lib/openmpi/1.4-gcc/lib:$LD_LIBRARY_PATH

in your .profile file to see if it solves the issue.

Best regards,

Hello,

no change with:

export LD_LIBRARY_PATH=/usr/lib/openmpi/1.4-gcc/lib:$LD_LIBRARY_PATH

I see in file RESU/summary.xxxx, no define for CS_MPI_PATH: ??

Kernel : /usr/local

Preprocessor    :  /usr/local/bin

Hello,
Do you have the config.log files from the build directories of the FVM library and of the NCS kernel ?

Hello,

What is the output of:

ldd /usr/local/lib/libfvm.so.0

and of:

nm /usr/local/lib/libfvm.so.0 | grep MPI

and finally:

ls /usr/local/lib/libmpi. /usr/lib/libmpi.
