Greetings nsreddy,

We'll need some more information in order to help you:

• Which OpenFOAM version do you have installed?
• How did you install OpenFOAM?
  The error message you've got suggests that you installed from Deb or RPM packages, but it also suggests that you installed said packages in an unsupported system.
• Which Linux Distribution are you using? Fedora, Ubuntu or openSUSE?
• Which version of that Linux Distribution?
• Which architecture of that Linux Distribution? 32bit or 64bit?
• Do you have more than one OpenFOAM installation installed? If so, how are you keeping them apart?

Best regards,
Bruno

Hi N S reddy,

That's a somewhat strange error you're getting... looks like the modem you're installing is either modifying or affecting Ubuntu's version of Qt, which leads ParaView to not work properly.

There are at least two possible solutions:

1. You can try and find how the modem software is affecting the Qt library. Run:
   

   cd /opt/paraviewopenfoam381/lib/paraview-3.8
   ldd ./paraview

   If you can show us the output from this last command, we might be able to diagnose where the problem is and what might be a good solution.
2. Or you can try and follow these instructions for replacing the ParaView version you've got installed: http://www.cfd-online.com/Forums/blo...-openfoam.html - these instructions will help you install the pre-built version of ParaView available at paraview.org, which already comes with its own Qt libraries.

Best regards,
Bruno
