Dear all,

I installed OpenFOAM-1.5-dev on Ubuntu 9.10 x86_64 and it all works swell, also paraFoam. That is, for single phase cases. When I run a multiphase case like damBreak or bubbleColumn paraFoam crashes with a segmentation fault. No error messages are given . When I convert the case to VTK and open it in ParaView, it still crahses with a segmentation fault. ParaView does give some error messages, although I can't really tie them to crashing for multiphase:

Fontconfig warning: "/etc/fonts/conf.d/11-lcd-filter-lcddefault.conf", line 9: invalid constant used : lcddefault
Fontconfig warning: "/etc/fonts/conf.d/53-monospace-lcd-filter.conf", line 17: invalid constant used : lcdlegacy
Segmentation fault

Does anyone have an idea what can cause this? Should I recompile the whole lot? Thanks in advance!

Is there a debug-switch for paraFoam?
If so, try to switch it on, and maybe you will get a more detailed error message.

Hi Sebastian,

Thanks for your reply. I don't know whether there is a debug switch in paraFoam. There probably is one, but haven't found it yet . I did some further digging and found that there is a problem with the graphics driver (fglrx_dri.so). It turns out that my work laptop has an ATI card and I read on the Ubuntu wiki that I should grab the latest kernel and find the Ubuntu open source driver for my ATI card. I did that, but no success. I also installed OpenSUSE-11.2 on the same laptop to see if it works, but no success either . Does anybody have experience of how to get ParaView working properly on a Lenovo W500 (ATI Radeon HD3650 DX10.1)?

I had some problems regarding the graphics drivers, too.
Just installing a new kernel and/or graphics driver didn't work out on my system.
I even had to recompile ParaView and the PV3FoamReader again.

Ok, so the recipe of

1. grab new kernel
2. install open source driver
3. recompiling ParaView
4. recompile PV3FoamReader

worked?

On my Ubuntu system this worked!

[gwierink]

With an ATI card? That would be great news!

I can't promise you THAT, but I made the experience, that changing drivers/kernels does not effect the current compilation of ParaView and the reader. I had to do it again ...

[gwierink]

I can't promise you THAT

That's a pity . I didn't recompile ParaView after installing the new driver, so I'll do that and see what happens. Thanks for your help .

This is just a message to log what I got working. Hopefully of some use to someone.

After some struggle with Ubuntu and OpenSUSE it got "kind of solved" . At the moment I have OpenSUSE 11.2 installed and it works very well. The main problems were (are) with the graphics card. I changed two things that got it working:

1. Install ParaView-3.4.0 instead of 3.6.2
2. Change the default graphics card in the BIOS

In the BIOS "config" > "display" section there are three values, these are the one that worked for me:

1. Default graphics card: "integrated" (was ATI)
2. Integrated/discrete graphics: "let OS choose" ("integrated" worked as well)
3. OS detection: "enabled" (but both "enabled" and "disabled" worked)

I guess the trick was to switch to integrated graphics card as default and use ParaView-3.4.0 ... Anyways, I'm happy it works now . Thanks, Sebastian, for your help.
