Hi,

I am working on a wind tunnel simulation using OpenFOAM, and I just installed version 3.0.1 on my computer. The case was initially created with version 2.3.0, so there are a few compatibility errors that came up. Some of them I could overcome already, but I am stumbling over this error, to which I couldn't find a solution.

When running blockMesh or surfaceFeatureExtract for example, following warning comes up:

--> FOAM Warning :
From function dlOpen(const fileName&, const bool)
in file POSIX.C at line 1179
dlopen error : libincompressibleRASModels.so: cannot open shared object file: No such file or directory
--> FOAM Warning :
From function dlLibraryTable:pen(const fileName&, const bool)
in file db/dynamicLibrary/dlLibraryTable/dlLibraryTable.C at line 99
could not load "libincompressibleRASModels.so"

It is not preventing the applications from running, but it would be nice to know how to fix it.

I suspect it has something to do with the fact that, in versions post v3.0.0, the keywords for RAS and LES changed. Am I right?

Thanks in advance for your help.

Nevermind, I have found the solution. This post can accordingly be deleted.

Same problem here! would you please share your solution?!?

Sure!

The turbulence models were renamed in versions post-v3.0 (RAS and LES not distinguished anymore, but generaluzed under "Turbulence Models".

You need to go to your controlDict file, in the system directory, and change "libincompressibleRASModels" to "libincompressibleTurbulenceModels". The warning should then disappear!

Hi.

One of our students is also getting the following in Openfoam30

FOAM Warning :
From function dlOpen(const fileName&, const bool)
in file POSIX.C at line 1179
dlopen error : libincompressibleRASModels.so: cannot open shared object file: No such file or directory

However, there doesn't appear to be any reference to libincompressibleTurbulenceModels or libincompressibleRASModels in /etc/controlDict just turbulenceModel & RASmodel as per the previously posted solution.

root@linux1:/opt/openfoam30# find ./ -name controlDict -exec grep -E 'RAS|turbulence' /dev/null {} +
./etc/controlDict:    DispersionRASModel  0;
./etc/controlDict:    GradientDispersionRAS   0;
./etc/controlDict:    RASModel            0;
./etc/controlDict:    StochasticDispersionRAS 0;
./etc/controlDict:    dispersionRASModel  0;
./etc/controlDict:    gradientDispersionRAS   0;
./etc/controlDict:    stochasticDispersionRAS 0;
./etc/controlDict:    turbulenceModel     0;
root@linux1:/opt/openfoam30#

any suggestions gratefully received!

thanks.
