Greetings to all!

Since today is a holiday here in Portugal, I took the liberty to do some preemptive testing of installing OpenFOAM 2.1.1 on Ubuntu 12.10 aka Quantal, which has recently reached beta stage.

Problems installing on this new release was expected, so I've added instructions for it here: http://openfoamwiki.net/index.php/In...u#Ubuntu_12.10


I did the tests only on a virtual machine with Ubuntu 12.10 x86_64 and everything built without any problems, as long as those instructions are properly followed
Nonetheless, I'm expecting problems with real machines, because graphics card drivers can be a serious pain sometimes...

Anyway, if anyone has problems installing and using OpenFOAM 2.1 and ParaView 3.12.0 on Ubuntu 12.10, feel free to use this thread!

Best regards,
Bruno

Hey there,
i have a big problem with this installation.
it seems like everything went well and when i try to do the first tutorial showing the mesh with paraFoam it generates an error telling me about segmentation violation.
opening paraview is possible, but not paraFoam.

i have an laptop with the NVIDIA GeForce 9300M G.
it does not work either with proper driver installed or with default one.

some ideas or same problems?

thanks a lot!

Greetings Michael,

I was expecting that sooner or later someone would report problems with an NVidia or ATI card

So, let's try and isolate the problem:

1. Try using the internal reader:
   

   paraFoam -builtin

2. Do you have another installation of ParaView in your Ubuntu installation? Or in other words, have you installed Ubuntu's default ParaView?
3. With either ParaView, try creating a new object. In the menu "Source", choose "Sphere" and hit the "Apply" button. Does it also give a segmentation fault?
4. If you haven't tried Ubuntu's own ParaView, then install it. You can install it by running:
   

   sudo apt-get install paraview

   Then go into the case folder you were testing before and run:
   

   paraFoam -builtin -touch

   Then open ParaView via the global Ubuntu menu (or whatever they call it now "dashboard" maybe?). And open the created file, possibly named "cavity.foam" in the case folder you were testing in.

Depending on the outcome of these tests, we should be able to figure out a solution!

Best regards,
Bruno

Dear All

I have installed open foam 2.1.1 on unbuntu12.10 with the help of hack that bruno provided i.e change precise to quantal but the problem is when I try to post process my results in paraview it gets crashed.If some one has done the cavity tutorial so for them when I reach the step where I try to got to the filters the moment I click it it crashed.Can any one help me on this

Greetings Muhammad and welcome to the forum!

Try these steps:

1. Switch to "root" mode:
   

   sudo -s

   Or:
   

   su -

2. Uninstall OpenFOAM's ParaView and install Ubuntu's version:
   

   apt-get remove paraviewopenfoam3120
   apt-get install paraview

3. Go into the folder where OpenFOAM is installed, more specifically to the "bin" folder it has got. If I'm not mistaken, it should be in your case:
   

   cd /opt/openfoam211/bin

4. Now run these two commands:
   

   sed -i -e 's/requirePV=1/requirePV=0/' paraFoam
   sed -i -e 's=\.OpenFOAM=\.foam=' paraFoam

   The first command is just a precaution.
5. Exit "root" mode:
   

   exit

6. Go to one of the folders where you have an OpenFOAM case and try running paraFoam in it. It should now work as intended!

Best regards,
Bruno

Hi Muhammad,

Looks like you need to install the correct drivers for your machine's graphics card!
Search online through Google or some other search engine, for the following keywords:

install graphics card drivers in Ubuntu

Good luck!
Bruno

I changed the VERS to precise and everything worked fine for me last night.
As a beginer for Ubuntu and OpenFOAM, I have tried such a long time to install OpenFOAM. Finally it worked. So, thanks for your help, Bruno!

I did paraFoam in cavity case and everything went well.

then I suppose that you can do paraFoam in every tutorial case, right? I tried to do paraFoam in some other case directories, it did not work.
the error of paraview said that there are some error in line so and so, or invalid mesh or something like that.
I just want to know it that normal for some cases in tutorial?
Or do I have problems with my installation if that happened?
Thanks for your help!

Greetings Peter and welcome to the forum!

First, read the user guide and follow the detailed tutorials there: http://www.openfoam.org/docs/user/tu...s.php#x4-30002

Then, depending on the tutorial:

1. Look for a file named Allrun in the case's folder or parent folder. If there is one, you can run it with:
   

   ./Allrun

   Feel free to edit the file, to learn which commands are used.
2. If there is none, simply run:
   

   foamRunTutorials

Only then can you use paraFoam.

Bruno
