I've installed OpenFOAM from binaries:

• OpenFOAM-1.6.General.gtgz
• OpenFOAM-1.6.linux64GccDPOpt.gtgz
• ThirdParty-1.6.General.gtgz
• ThirdParty-1.6.linux64Gcc.gtgz

Unpacked these files in /home/OpenFOAM

run:
export FOAM_INST_DIR=/home/OpenFOAM/
. /home/OpenFOAM/OpenFOAM-1.6/etc/bashrc

then following the "2.1 Lid-driven cavity flow" tutorial
tut (because $FOAM_RUN/tutorials/incompressible/icoFoam/cavity does not exist)
cd incompressible/icoFoam/cavity
blockMesh
and then, to see the mesh:
paraFoam -case /home/OpenFOAM/OpenFOAM-1.6/tutorials/incompressible/icoFoam/cavity


I answer I want to open "OpenFOAM Files" and I get the error messages:
NVIDIA: could not open the device file /dev/nvidiactl (Permission non accordée).
NVIDIA: Direct rendering failed; attempting indirect rendering.
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_S_create
/home/OpenFOAM//OpenFOAM-1.6/bin/paraFoam: line 109: 22727 Abandon paraview --data="$caseFile"

and:
# ls -l /dev/nvidiactl
crw-rw---- 1 root video 195, 255 janv. 27 07:51 /dev/nvidiactl
# groups
turb visiteur cvsgroup stagiaire book postdoc trio triobin video


Any idea ?

Thanks

Hi Patrick,

It probably happens because you need to build ParaView and (especially) the PV3FoamReader. The line

/home/OpenFOAM//OpenFOAM-1.6/bin/paraFoam: line 109: 22727 Abandon                 paraview --data="$caseFile"

shows that the shell has a problem with the paraview command. So, I would suggest to follow the README instructions to build Qt and ParaView (including the reader).

This is a typical message that you get if you've loaded files with '.foam' and not '.OpenFOAM'. The '.foam' is the default OpenFOAM reader built into VTK and previous versions are buggy (the forum and paraview lists will also mention this). A newer version (from Takuya Oshima) is now in the ParaView CVS/git (eg, http://github.com/Kitware/ParaView) and shouldn't have this problem. The library-based reader included in OpenFOAM itself (uses the '.OpenFOAM' extension) is not know to have this problem.

This is a typical problem associated with the nvidia driver. You either need to add yourself to the video group (okay if your user is local and not NIS) or simply adjust the nvidia permissions accordingly (this is what we do).

• look for the file /etc/modprobe.d/nvidia or /etc/modprobe.d/NN-nvidia.conf (depending on your installation and driver version).
• let everyone with access to the workstation use the video driver (presumably the rest of your firewall is okay). Edit the file to have NVreg_DeviceFileMode=0666 permissions.
• you can manually adjust the permissions chmod 666 /dev/nvidia* but you'll generally need to either reboot or use init 3 followed by init 5 to retain the changes. If you don't do this, the kernel module remains loaded and will continue to use the old permissions at the next xdm/kdm/gdm user login.

Finally, if you will be working with OpenFOAM, be sure to get the patches and fixes that are contained in the git repository: http://repo.or.cz/w/OpenFOAM-1.6.x.git

Thanks for your detailed answers. So you mean that the binary distribution of OpenFOAM 1.6 is not operational and that I have to rebuild the binaries from the last availables sources
My idea was just to use the PC for visualisations without the need to compile again OpenFOAM 1.6.x (I compile it on an Altix for the simulations and I'm not allowed to run graphic applications on it)


About nvidia, I have the group video (see the groups command). This is why the message is strange....

Lets go for a full OpenFOAM 1.6.x compilation now!

You only need the git version if you want a version with bugfixes in it.
You'll be the only one who can tell if the various bugfixes are important to you or not.

Problem solved.

I want to thanks all for your suggestions. The problem was with the binaries of OpenFOAM-1.6 & ThirdParty-1.6 not working on my computer
openSUSE 11.0 (X86-64) Linux 2.6.25.20-0.5-default #1 SMP.

I've ran
wcleanAll
./Allwmake
in the toplevel directory and after a couple of hours of compilation, all is working fine immediatly.
No need of any patch!

Thanks again

Hello to everybody
I've installed OpenFOAM from binaries:

• OpenFOAM-1.6.General.gtgz
• OpenFOAM-1.6.linux64GccDPOpt.gtgz
• ThirdParty-1.6.General.gtgz
• ThirdParty-1.6.linux64Gcc.gtgz

Unpacked these files in /home/OpenFOAM
I run the foamInstallationTest script with no critical error but one warning:
Third party software
-------------------------------------------------------------------------------
Software Version Location
-------------------------------------------------------------------------------
WARNING: gcc version does not match gcc supplied with this release of OpenFOAM

Summary
-------------------------------------------------------------------------------
Base configuration ok.

Critical systems ok.

When i try to run the cavity tutorial, blockmesh works well but when i try to see the mesh with parafoam, paraview open a the cavity.foam (created temporary 'cavity.OpenFOAM') but i don't see the results.

I would be very grateful if someone can help me

Best regards
