Memory segmentation fault on CentOS 5.5
 
I have installed STAR-CCM+ 5.06 on a fresh CentOS 5.5 install.

The installation seemed to go ok, but trying to create (or open) a project causes segmentation fault.

The output in StarCCM+ shows:

Code:

Starting local server: /opt/starccm/starccm+5.06.010/star/bin/starccm+ -server
/opt/starccm/starccm+5.06.010/star/bin/starenv: line 1253: 17329 Minnesegmentsfeil      "$@"

No information is dumped to the terminal.

I have tried serial and parallell processing, but nothing works.

Any ideas?

Edit:

/var/log/messages:

Try running memtest86+ and seeing if you get any memory errors...

Bauer January 21, 2011 18:52

30 minutes of memtest86+ shows no errors, however I will run a more extensive test tomorrow.

If it is of any relevance, now I noticed this getting dumped to the terminal while starting starccm+
Code:

java.net.UnknownHostException: Bauer: Bauer
        at java.net.InetAddress.getLocalHost(InetAddress.java:1354)
        at org.netbeans.CLIHandler$1.run(CLIHandler.java:559)
        at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:602)
        at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1084)

Edit:
Another 2-hour test gives no errors.

Turns out it works without problems on Ubuntu, so never mind :)

I had to install my new machine (i7-2600) and tried different Linuxes. Here are my observations:

Ubuntu 10.04: ccm+ works but very slow, starcd crashed
Suse 11.3: ccm+ crashed (as described above) but starcd workes and also fast
Suse 11.1 and 11.2: both codes work and also with the expected speed.

Can you give a bit more info on your "study" specifically on Ubuntu? How much slower was ccm+? Was it just slower loading, meshing, when solving, or everything?

Thanks for info

Ubuntu was about half the speed compared to Suse running on 1 and also on 2 cores. Probably something went wrong with the installation. But since StarCD (v3 and v4) did not really run I did not try to resolve the other problem.
