Segmentation fault when visualizing in ParaView
HI Everyone!! I have this problem. I installed the latest release of OpenFoam (1.7) in Linux 10.4. Everything works good, except when i go to ParaView. I excecute paraFoam, and ParaView runs correctly. When i select some part of the mesh and click "Apply", it closes and i gete the error:
Segmentation fault. And thats it, it doenst work for any mesh, for any case. Any ideas? Thansk!!!! |
Greetings Fernando,
OK... firstly, is Ubuntu 10.04 is a Linux distribution ;) Now, as for the issue you are getting... What were exactly the steps you did before running paraFoam? Did they include either one of these commands: Code:
blockMesh If not, don't expect to have a ghostly mesh, because OpenFOAM doesn't do ectoplasm... or at least I don't think it does :D Are you following OpenFOAM's official User Guide? See here: http://www.openfoam.com/docs/user/tu...s.php#x4-30002 I'm sorry for seaming a bit goofy in my answer, but with the information you provided, I can only infer that the steps you took prior to running paraFoam were the wrong ones, if any :( Best regards, Bruno |
Ok, maybe i didnt give too much details.
I have been using openfoam for some time. The thing is that last week i installed it on a new server we boguht. What i am trying to do works perfectly in another computer. I use meshes cretaed by netgen and correctly exported to openFoam. Before trying to run paraFoam, i run the simpleFoam solver, with the correct bounday conditions and everything ok. In any other computer, with OpenFoam 1.6 i can visualize results with paraFoam. Now, in this new installation, with this new version 1.7, in Ubuntu 10.04, i get this problem. Not only with my cases, but with any tutorial. Any ideas? |
Hi Fernando,
OK, what versions of OpenFOAM and of ParaView did you install? Was it:
Because "segmentation fault" could be from many things:
So, the better you can describe the steps you took to install OpenFOAM, the better chances are that we can isolate the actual problem! Best regards, Bruno |
Hi! Thanks a lot! I tell you.
Ubuntuīs installation is a fresh clean one, downloaded form Ubuntus webpage installed as 64 bits in ENGLISH. For openFoam and paraView installation, i followed all the steps in: http://www.openfoam.com/download/ubuntu.php I guess that would be the ones with openfoam170 and paraview380. And thatīs it. Once the installation was completed, i tested it with one tutorial and with one of my cases and it worked. After restarting, ir didnt work anymore. Thanks a lot, i am a bit stucked with work :( Greetings |
Hi Fernando,

If my deduction is correct, then you can:
There is also the possibility that before you rebooted, you actually told Ubuntu to install the graphics card drivers, thus making ParaView to malfunction. There is yet another possibility: if visual effects have been turned on, then turn them off again. Right click on the Ubuntu desktop, "Change Desktop Background" and on the last tab named "Visual Effects", select "None". Finally, if neither one of these worked, then uninstall paraview380: Code:
sudo apt-get remove paraview380 Then go to your tutorial case in a terminal and run: Code:
touch case.foam
If opening with the official pre-built ParaView 3.8.0 + case.foam didn't work, then there is the final solution - install Ubuntu's ParaView 3.4.0: Code:
sudo apt-get install paraview Code:

problems with paraView
Hi Bruno,
due to paraView and the new installation of openFoam 1.7 (i am using Ubuntu 10.04 LTS) i have the problem that paraView could open the geometry but it shows "anything" that means it shows a the geometrie itselfs but the grid is very big and nearly the same in any geometry i opend. If i open the same case on a computer where i installed openFoam 1.6.x and paraView 3.6.1 the grid is okay. Maybe you have an idea how to solve this problem. Thanks! Best regards, Claudia |
Greetings Claudia and welcome to the forum!
I'm going to have to recycle a recent post of mine - the solution for your problem should be here: http://www.cfd-online.com/Forums/ope...tml#post267265 Best regards, Bruno |
