Error at creating a mesh

[herbk]

Hi,
At trieng to generate a mesh i get the error mesage

Code: Select all

/opt/openfoam-1812/etc/config.sh/mpi: Zeile 53: mpicc: Kommando nicht gefunden.
gmshToFoam: error while loading shared libraries: libmpi.so.12: cannot open shared object file: No such file or directory

The file is availible, so i'm in mind, that FC is surching at a wrong path... Where it has to be? At my system it is at /usr/lib64/mpi/gcc/openmpi/lib64/
libmpi.so.12 is only a link to libmpi.so.12.0.7, - may be that's the problem?

On some systems the MPI libraries and executables are not added to the relevant paths when they are installed. On mine, I created a custom.sh file in /etc/profile.d containing the following:

Code: Select all

PATH=$PATH:/lib64/openmpi/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib64/openmpi/lib

I'm guessing for you it would have to be something like:

Code: Select all

PATH=$PATH:/usr/lib64/mpi/gcc/openmpi/bin
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/mpi/gcc/openmpi/lib64

Note that this is more an issue with your MPI and OpenFOAM installation rather than FreeCAD and CfdOF per se. There should be information available for your version of Linux.

Hi Oliver,

thx for the info, i will try today evening..

Note that this is more an issue with your MPI and OpenFOAM installation rather than FreeCAD and CfdOF per se. There should be information available for your version of Linux.

Thats my mind to...

I'm setting up a new System with OpenSuse Leap 15.1. It's at beta state, but the conection FC - Openfoam seams to work better as at the before used Leap 42.3...

Hi Oliver,
i still got the same error if i put in a "custom.sh" with the contend you are guessing.

But i noticed,, that there is a file "mpi-selector.sh" and a "mpi-selector.csh in /etc/profile.d. Both have the same contend:

Code: Select all

mpi_selector_dir="/var/mpi-selector/data"
mpi_selector_homefile="$HOME/.mpi-selector"
mpi_selector_sysfile="/etc/sysconfig/mpi-selector"

mpi_selection=
if test -f "$mpi_selector_homefile"; then
    mpi_selection=`cat $mpi_selector_homefile`
elif test -f "$mpi_selector_sysfile"; then
    mpi_selection=`cat $mpi_selector_sysfile`
fi

if test "$mpi_selection" != "" -a -f "$mpi_selector_dir/$mpi_selection.sh"; then
    . "$mpi_selector_dir/$mpi_selection.sh"
fi

I will ask at a OpenSuse forum for it....
