Segmentation Fault in Starter
Posted 23 December 2008 - 05:02 AM
I'm trying to benchmark a m/c with a Radioss model. I have run simple jobs on it OK but when I try to use more complex jobs the starter module fails with a segmentation fault. The model I have been given has run on other machines.
I have tried other, larger models (downloaded from the Altair website) and a similar thing happens only earlier in the data check process.
Has anyone had a similar experience?

The issue is probably related to stacksize of the machine.
If you set stacksize to unlimited - the starter should run through with any segmentation issues.
If it's a linux machine, depending the shell this is how you set stacksize
in csh SHELL
to know all limits, type :
To set the Stacksize to unlimited type :
the command to know all limits is :
to set the Stacksize to unlimited type:
ulimit -s unlimited
Hope this works

I would like to open this thread again, since I am having a similiar problem.
With one particular model of mine I keep getting a "segmentation violation" error
a section of the output file:
The error almost seems to occur randomly, however only with one particular model so far.
Sometimes the solver runs, but mostly it doesnt.
Since I use windows I have done the settings as suggeted by the radioss user guide. (KMP_STACKSIZE = 64m).
However it doesnt seem to help.
Is there anything else I could do to fix this?

Now, keep having this problem when I try to run a HyperStudy analysis.
When I run the model file just by itself with radioss it works. However, if I want to do the nominal run in HyperStudy I get the same segmentation violation error.
What could it be?

Have you tried dos2unix conversion? Maybe it could help. I was experincing a problem like that and dos2unix conversion helped me alot.
Another thing is keep your solver executables and c/c+ libraries up to date.

I am trying to solve an explicit problem with Radioss and having similar problem. When it comes to "GROUPS" it gives this error and terminates the job. Any advice?
