Hello World

I try to run my first simulation using the tutorial cavity and unfortunately i can see only the mesh and i cannot apply the file cavity in paraview.

After writing the command paraFoam i became an Error( 7 lines ) at the end of terminal :

QVariantMap DBusMenuExporterDBus::getProperties(int, const QStringList&) const: Condition failed: action

I use Ubuntu 12.04, paraview 3.14.1 64-bit and Openfoam 2.2.0

How can i solve the problem?

Thanks .

Hi everyone,

i have the same problem and i cannot apply the openfoam file's in paraview, i installed paraview from the openfoam website http://www.openfoam.org/download/ubuntu.php and i added an alias command to my "~/.bashrc" file the code
alias paraFoam='paraFoam -builtin' but i couldn't solve the problem...

I use Ubuntu 12.04, paraview 3.14.1 64-bit and Openfoam 2.2.0

Thanks for your help!

Greetings Amin and welcome to the forum!

I moved the second post from the thread http://www.cfd-online.com/Forums/ope...r-message.html, because this first one you created on this current thread has got some additional information that comes in handy.

OK, according to your description, you have 2 ParaView versions installed:

• The one that Ubuntu provides, which is ParaView 3.14.
• The one that OpenFOAM provides, which is ParaView 3.12.

Given your current set-up, I advise you to choose one to keep and remove the other one:

• If you want to keep Ubuntu's ParaView version, run:
  

  sudo apt-get remove paraviewopenfoam3120

• But if you want to keep OpenFOAM's ParaView version, run:
  

  sudo apt-get remove paraview

I say this because they might be getting into conflict between them, where one is using the other one's libraries.

Best regards,
Bruno

Thanks a lot !
i removed paraview and i tried to installed from the website of Openfoam, but i couldn't. that is why i dowloaded it from the paraview website..and iT is working !
Thanks a lot ! Thanks a lot ! Thanks a lot ! Thanks a lot ! Thanks a lot ! Thanks a lot !

i can launch paraview by typing "paraFoam" in your terminal,but i cannot see the mesh or the file to apply why

i tried to execute the tutorial cavity... after building the Mesh with blockMesh and typing icoFoam... the file cavity.foam was not created.
will the file cavity.foam be created after typing paraFoam or after typing icoFoam and blockMesh ?
Thanks

Hi Amin,

Quoting from the official instructions for the Ubuntu deb packages - http://www.openfoam.org/download/ubuntu.php - the steps are:

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity 
blockMesh 
icoFoam 
paraFoam

It's paraFoam that creates the "cavity.foam" file. If you want to keep the file for later using it again, you can run:

paraFoam -touch

For more information:

paraFoam -help

Best regards,
Bruno

hello Bruno

when i type paraFoam, paraview is opened but i cannot see the file cavity.foam
in paraview.

I think, in my case....the paraFoam command can only open paraView, without creating the file .Foam

the two commands are not working. The output of paraview for paraFoam -help is

Cannot open data file " -help "

I followed also the same instructions to run Openfoam and paraview, but it seams to, that i have a problem on the liaison between paraview and openfoem. maybe..i have to change something in the parafoam file in the Folder bin of openfoam....
here is my parafoam file in Openfoam.

the file of paraview is saved in home ..maybe i have to move it in the file system...
the file name of paraview in home is not "Paraview" but "ParaView-3.12.0-Linux-x86_64", maybe i have to change the name of the file...

Hi Amin,

From your description, it looks like you also have a ParaView version that you got from www.paraview.org.
Please tell me what does the following command show you:

alias paraFoam

If it says something like:

alias paraFoam='~/Desktop/ParaView-3.12.0-Linux-x86_64/bin/paraview'

then edit the file "~/.bashrc" and change the respective line to:

alias paraFoam='paraFoam -builtin'

Start a new terminal and try again to run paraFoam inside the cavity folder.


If it still doesn't work, edit the file "~/.bashrc" once again and go to the line that has the alias for paraFoam, and change it to this:

alias paraFoam='touch case.foam; ~/Desktop/ParaView-3.12.0-Linux-x86_64/bin/paraview --data=case.foam'

Keep in mind to adapt the path to the "ParaView-3.12.0-Linux-x86_64" folder accordingly to what you have got.

Best regards,
Bruno

PS: sorry I edited your post, but it was only to move the code you had placed with paraFoam's script, into the "[CODE]" markers.
