Goodmorning,


I have problems with the command "paraFoam" and also "paraFoam -block", when I run them I obtain this:





FATAL ERROR: The official reader module for OpenFOAM data does not exist on
your system. This means that the version of ParaView you are using was not
compiled with OpenFOAM, or distributed with a packaged version of OpenFOAM.

For information on packaged versions of OpenFOAM/ParaView and compilation of
OpenFOAM/ParaView, see https://openfoam.org/download

Alternatively, you might be able to view your OpenFOAM data with the reader
module provided with ParaView by running:
paraFoam -builtin





Instead, "paraFoam -builtin" works, but why the others don't work?

Hello Francesca,
it seems paraFoam is not installed on your machine. You can check simply the installation path on Linux as follows:

$ which paraFoam
$ which paraview

There are two independently developed reader for OpenFOAM and ParaView!
1.) ParaView built-in OpenFOAM reader => vtkOpenFOAMReader
2.) OpenFOAM has with an alternative reader => PV4FoamReader

How have you installed OpenFOAM and what is your system configuration?
best,
Damian

Hello Damian!
Thank you for your reply!


Checking the paths with



which paraFoam
wich paraview


as you suggested, I get correctly the paths:


/home/francesca/OpenFOAM/OpenFOAM-7/bin/paraFoam


and



/home/francesca/OpenFOAM/ThirdParty-7/platforms/linux64Gcc/ParaView-5.6.0/bin/paraview



For the installation of OpenFoam and Paraview I followed the instructions from this websites: https://openfoamwiki.net/index.php/I...7/Ubuntu/18.04


I have Debian9 and I installed openfoam 7: there were no installation instructions of openfoam7 for debian, but the compilation ended up well, I think.
With "system configuration" do you mean these info,

right?





How can I check if I have those reader you meant? And how can I install them?





Thank you in advance!!

ok, it seems both versions are at least available on your machine!
What are you trying to do? To open some OpenFOAM simulations results?
It should work also with the paraview version and created empty case.foam file in your simulation folder.
Check also this thread here in the forum:
paraFoam command no longer working after upgrading to Ubuntu 13.04
Have you added the

source /opt/openfoam7/etc/bashrc

at the end of your ~/.bashrc file?

I believe it should be:

/home/francesca/OpenFOAM/OpenFOAM-7/etc/bashrc

which should be added to the ~/.bashrc file.

Hey,


I do get the same first error, but using the "which paraview" demand I get nothing...


checking your link:
/home/francesca/OpenFOAM/ThirdParty-7/platforms/linux64Gcc/ParaView-5.6.0/bin/paraview

I noticed, that I don't have a ParaView-file under linux64Gcc... I do have one under ThirdParty-7, but this one doesn't include a bin-file... so I guess that is the problem, but I've no clue how to fix it.
Can anybody help? (:

Hi,
I am novice, but maybe the problem - or better solution - is as simple as it was in my case:

Originally, I encountered the same issue (of8 installed, no reply on <which paraview>). I suspect the installation procedure of of7 or of8 did not install paraviewopenfoam56 appropriately, because of5 and of6 with paraviewopenfoam54 were already intalled.

For the installation I followed the instructions on https://openfoam.org/download/8-ubuntu/. To make of8 work pretty well with of56 anyway, I simply executed <apt-get -y install paraviewopenfoam56> afterwards.

Maybe this is a solution.

Best
Nico
