I installed and ran paraFoam as in:
http://www.opencfd.co.uk/openfoam/li...tml#linuxAMD64

I also did the same on remote cluster but I recompiled the code using Allwmake. I ran the code no problem. But when I try to start paraFoam on the case result, I get the following error:

ParaView error: InitializeTcl failed
Tk_Init error: no display name and no $DISPLAY environment variable

If I try to run it from other node except the main one, I get the following error:

paraview: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

I tried to look for libGL.so, I could not find it neither on the remote nor local version that is still working.

Thanks,
Marwan

Problem solved.
