ParaFoam crash, wireframe
 
Hi all,

Iīm trying to visualize my mesh and i have some problems. I open ParaView 3.10.1 64-bit with my case. In the tab "properties" i have the mesh parts and the volume fields, I click to apply to load the internal mesh as well as the pressure and velocity field.

It seems to work, I can visualize my geometry with style<representation<outline . But if I switch it to Wire-frame, the program is blocked, paralyzed.
Do you have some idea about why I have this problem ?

Another point, itīs that in the display menu i canīt choose to show pressure or velocity, although in the information tab, there are these fields, I means, it seems that the data were uploaded....

Thanks everyone,

Greetings CRT,

In my blog here at cfd-online you'll find this post: Related issues to ParaView with OpenFOAM - Fixes and solutions - hopefully you can find the solution in the links provided there.

Either way, my diagnosis from your description is that something isn't connecting properly between ParaView and your graphics card, so there are two possibilities:
  • Bad OpenGL drivers, which basically is because of bad graphics card drivers. Either upgrade or downgrade your drivers, since it has been know in the past that new drivers sometimes bring problems instead of fixing them.
  • The connection between your ParaView version and your OpenGL drivers might be wrong. The solution here should either to rebuild ParaView from source or try to use ParaView that is provided by your Linux Distribution.
Best regards,
Bruno

Hi Bruno,

I was trying to use different drivers for the graphic card as well as another graphic card and it wasnīt work. A college found that the paraFoam program block a routine of Linux, thatīs something that shouldnīt happen. I mean, if thereīs a problem with the graphic card, etc. the program should be block, closed o whatever, but It shouldnīt block the whole system.

Searching in internet he found people with the same problem, their purposed solution was to upgrade the version of SUSE, and recompile the programs, paraFoam and OpenFoam. Furthermore Iīm using my graphic card without the official drivers.

Now I can visualize my mesh perfectly, but the second problem is still there

If you're not using the official drivers, then you're bound to sooner or later have serious problems :(

You can also try running:
Code:

foamToVTK
It will export the data to VTK format; then try opening the VTK files directly in ParaView.

Best regards,
Bruno
