paraFoam command gives an error
 
Hi all

I am running both OpenFOAM 4.1-extend and 6.0 on Ubuntu 18.04. When I run a case via of6 and execute paraFoam, everything works as normal. However, when I run a case via of4 and execute paraFoam, I get the error

Code:
Cannot use ParaView reader module library (PVFoamReader)
The PV_PLUGIN_PATH environment value is not set

Continuing with builtin reader:  paraFoam -vtk

Created temporary 'damBreakFine.foam'
/home/josh/foam/foam-extend-4.1/bin/paraFoam: 324: /home/josh/foam/foam-extend-4.1/bin/paraFoam: paraview: not found
I downloaded of4 here but did not yet execute section 1.3, since I already have paraFoam downloaded. Do I need to follow these instructions? If so, will they inhibit the of6 paraFoam that currently works?

Thanks so much!

What is wrong with using the regular builtin OpenFOAM reader? Apart from some face/cell sets (which you can convert with foamToVTK) it handles things quite well. You may have to skip the 0/ directory if you have lots of #include, code stream etc, but that is to be expected.
The only place where the additional special-purpose readers might be useful is for diagnosing complicated blockMeshDict.
Otherwise I just use the following:
Code:
alias parafoam='touch log.foam; paraview log.foam'

When I execute the suggested paraFoam -vtk , which I assume is what you're referring to, I still get the error

Code:
Created temporary 'damBreak.foam'

So inputting this at the end of the bashrc will allow paraFoam to work with of4 and of6 in the same manner (after a simulation, simply execute "paraFoam"?).

sudo apt-get install paraview ?

I have paraview installed (it works with openFoam 6). But it does not work with openFoam 4.

More specifically, at the end of the bashrc file I have
Code:
alias of6='source /opt/openfoam6/etc/bashrc'
alias of4='source $HOME/foam/foam-extend-4.1/etc/bashrc'
When I execute " of4 " the case runs, but executing " paraFoam " gives the the aforementioned errors, and nothing loads. However, if after running I open a new terminal, execute " of6 " and then execute " paraFoam " everything works. I'd like to be able to run paraFoam without having to open a new terminal everytime.

I meant that you can use your system paraview. Eg, on my ubuntu system
Code:
$ which paraview
/usr/bin/paraview
Or download a binary from https://www.paraview.org/download/

Do neither of these work?

This opens paraview but it does not allow me to load the simulation. Any ideas?
