Sudden errors: "cannot open shared object file: No such file or directory"
 
I had been simulating a 3d object with simpleFoam on a version of the motorbike tutorial, using OF 2.3.1

After many runs, and a small change to the input geometry, it started throwing this error,

dlopen error : libincompressibleTurbulenceModel.so: cannot open shared object file: No such file or directory

the error persists even after restoring the input with a backup the had just run with no errors.

Has anyone seen this before?

This has nothing to do with your case. Your OpenFOAM installation is broken.

I uninstalled OF2.3.1, and installed a fresh copy of OF3.0.0.


Same error

Hi,

Guess, your case files contain somewhere a line (or similar)

Code:
libs ("libincompressibleTurbulenceModel.so");
In 3.0.x this library was removed:

Code:
$ echo $WM_PROJECT_VERSION
3.0.x
$ cd $FOAM_LIBBIN
$ ls -1 *Turbulence*
libDPMTurbulenceModels.so
libcompressibleTurbulenceModels.so
libincompressibleTurbulenceModels.so
liblagrangianTurbulence.so
libmultiphaseReactingTurbulenceModels.so
libphaseCompressibleTurbulenceModels.so
libtwoPhaseReactingTurbulenceModels.so

Problem is, it stated doing it before I swtched to OF3.0.0

Well, then, I guess, someone just deleted the library. And I have checked tutorial controlDict, in 2.3.1 it does contain these lines:

Code:
libs
(
    "libOpenFOAM.so"
    "libincompressibleTurbulenceModel.so"
    "libincompressibleRASModels.so"
);
So there are plenty of possibilities for the error, and there is almost no information for diagnostics.

I had this problem when I moved from 2.3x to 3.0x.

It is my understanding that 3.0x does not use them, so I commented out those library references in my ControlDict when using 3.0x.

However, the file with these libs left in the ControlDict should work in 2.3 as they did for me. The most possible problem is that they are not in your lib bin in 2.3 when they should be. I think Alexey is right.
