Hi,everyone,i installed OpenFOAM2.1.0 and paraview3.12.0,but when i use paraview ,sometimes there occurring segment fault.who can give me some advice to overcome this error.Thanks a lot.

Greetings hei@ge,

Try this:

paraFoam -builtin

I've seen the built-in reader being more stable than the official OpenFOAM reader.

Best regards,
Bruno

Hi，first,thank for your replying .I think that paraFoam -builtin is just a way of open case in the root of case.I use paraFoam in the root of case,then i get the fault.

Really? You don't believe me?? Then try this to see if I'm right or not:

paraFoam -help

sorry，i did not mean that.i have tryed it .but there are some problem.because my case is not decomposed.How can i use paraFoam -builtin in my case which is not decomposed?Thanks a lot.

No problem! But I think you aren't seeing very well how the built-in reader works.
The built-in reader can open both kinds of cases, namely decomposed and cases that have not been decomposed!
So I don't understand what kind of problem are you getting... any chance you can post a snapshot of the problem you are getting?

I use paraFoam -builtin open my case,and i chose "reconstructed case".Then i get a message: p, li { white-space: pre-wrap; } line 6481

Can you give me some advice,Thanks very much.

Unfortunately, I'm also facing problems with using paraFoam. I had reinstalled OpenFOAM 2.1 and ParaView 3.12 from source build as described on OpenFOAM website.

Especially, when I tried to use Plot over Line, paraFoam is crashing on my Ubuntu 10.04, from CAELinux. The following message gets displayed

X Error: BadRequest (invalid request code or no such operation) 1
Extension: 154 (Uknown extension)
Minor opcode: 182 (Unknown request)
Resource id: 0x3e02d9d
paraview: ../../src/xcb_io.c:183: process_responses: Assertion `!(req && current_request && !(((long) (req->sequence) - (long) (current_request)) <= 0))' failed.

I tried Bruno's proposal to use paraFoam -builtin, but the problem still persists. Any suggestions will be highly valuable.

Thank you.

[hei@ge]

The problem is still confusing me .When i solve it ,I will tell you how to do it.

Hi hei@ge and Sam-CFD,

hei@ge: OK, now we are getting somewhere. Your problem is related to a filesystem problem or locale interpretation problem. A few more questions:

• Do you have OpenOAM installed inside a virtual machine? And if so, is the folder of your case being shared with the real machine?
• Is your Linux installation done in your native language or in English?

Sam-CFD: The drivers for your machine's graphics card are probably not properly installed.
The other possibility is due to one of several glitches that occurs every once in a while:

• Usual problems with ParaView and some hints on how to fix them: Segmentation fault when visualizing in ParaView
  Also check this one: ParaView Subwindow Crash
• ParaFoam error could not find a decent visual - solution in post #4

Best regards,
Bruno

[Sam-CFD]

Thanks Bruno. The Plot over Line is working for me perfectly.

My problem was fixed after rebooting. It seems after installing the Graphic drivers, I hadn't rebooted my machine yet.

[hei@ge]

Thank you,Bruno.I install double system:my host machine is XP,and i install ubuntu10.04 in the F disk. My ubuntu10.04 's language is chinese.In my p case,there is one symbol "$",whether the symbol of $ is too new for reader to recognize it?

[wyldckat]

Hi hei@ge,

Indeed, it's very possible to be a problem with locale. The usual fix is:

export LC_ALL=C

Before running the applications that need an English locale. But it seems that lately this doesn't always work.

Best regards,
Bruno

[hei@ge]

Thanks a lot .I think some warnings do not always influent the process of the simulation,right?

Depends on what the warning message says
