PV3FoamReader does not exist
 

Hello, the installed version of OpenFOAM is 'OpenFOAM-v2112'
Installed paraview version is 'ParaView-5.6.0'
Installed Qt version is 'Qt5.12.4'
I work on HPC machines so i dont have sudo permission but i can make IT do commands.

I want to open paraview with paraFoam reader. Therefore , i try to build the reader module before continuing:
cd $FOAM_UTILITIES/postProcessing/graphics/PV3Readers but i cant find PV3Readers modules at all!

Is there anyone who can help me why it does not exist?

You appear to have something really weird with your setup. The message about "graphics/PV3Readers" does not make any sense whatsoever. Not only are we well beyond ParaView-3 (tk-based if I remember correctly), but all of the visualization stuff has been moved out into a separate module as well. This was done to improve flexibility (can recompile with different rendering backends and different paraview or vtk versions).

Some information is available on the corresponding wiki page:
https://develop.openfoam.com/Develop.../visualization

Can either work from the git repo, grab the sources out of the OpenFOAM source pack, or get the module sources separately:
https://dl.openfoam.com/source/latest/ (eg, OpenFOAM-modules-v2112.tgz)

However, I strongly suggest that you read the comments on the wiki:
https://develop.openfoam.com/Develop...raview-plugins
https://discourse.paraview.org/t/i-w...n-should-i-use

I, for one, use the builtin reader almost exclusively. It is still a bit rough around the edges with respect to handling zones (would like to address that in https://gitlab.kitware.com/vtk/vtk/-/issues/18157 which needs resources to tackle) but otherwise fairly complete.
