ParaFoam BadLength error
 

Hello all,

I have installed OF1.4 and I have run some of the tutorial cases. I then used paraFoam to view thw results but when I try to create and animation or save a figure paraFoam closes and reports:

paraFoam . shockTube

Has anyone else experienced this? Any idea how this problem can be fixed.

Thanks,

Hello. Paraview works OK for m
 

Hello. Paraview works OK for me. It seems a problem with your OpenGL libraries.

Are you using accelerated drivers for your video card?

Hi,
Thanks, it's so encouraging to know saving images works at least in a case.
I have to stick with the open-source driver to use a dual-head merged framebuffer setup with my old Radeon 9200 video (the merged framebuffer of the vendor-supplied driver doesn't work). The rendering itself works fine but just saving images makes paraFoam crash.
Maybe I should consider replacing the video card...

Hi,

I had used openFaom 1.3 with no problems, I was able to create and save animations and also images, but since I upgraded to OpenFoam 1.4 I haven't been able to save the images and animations. I will need to look into the OpenGL libraries but it did work with the older version!

FLUENT have similar issues wit
 

FLUENT have similar issues with some nVidia cards, if you don't have installed the accelerated nVidia drivers.

If this is the case, your you find a tutorial to install them using RPM's provided by Novell: http://en.opensuse.org/NVIDIA

Greetings everyone! My Lapt
 

Greetings everyone!

My Laptop has an Intel GMA chipset (onboard graphics). I think I have found a workaround to this IRRITATING GLXBadContext error. Based on my google search, I tried one of the suggestions from the freedesktop.org thread[1] and it solved my problem instantly. There is no need to recompile paraview and/or parafoam by commenting out the two offscreen rendering lines as discussed elsewhere[2].

The proposed workaround is to add the following line to the 'ServerLayout' section in your /etc/xorg.conf. Please make sure to create a backup before you modify it.

For Example:

Section "ServerLayout"
Option "AIGLX" "false"
EndSection

FYI: The other way to work around this problem is to disable OpenGL acceleration by using the software cursor [Not recommended!].
