I finally have found the time to install it.
But I am getting some troubles in sort out this issue.
I have installed on a virtual machine OpenFOAM-8 and Paraview v5.6.3 packaged in a Linux OpenSUSE distribution.
Now, I updated Paraview with the newest version 5.9.0, as you suggested. I downloaded the source code, compiled it in the Third Party directory with makeParaview, and the installation was completed successfully.
Paraview v5.9.0 opens up properly when running the script paraview in the respective folders (by manually clicking on it or in a new terminal after I updated the .bashrc file with the proper environment variables).
But when in a shell terminal, where OpenFOAM is running, I type Paraview or ParaFoam this opens up again the version 5.6.3 of Paraview, and not the latest one installed in the same directory.
How can I link Paraview 5.9.0 to OpenFOAM to get the proper Paraview/ParaFoam working?
Thanks in advance for your help.
