simble beam and error: "floating point exception" was created by Erkki Holopainen
Hello!
I'm new to CAELinux and I try to analyse displacement and stresses of a simple single beam case.
Code Aster gives me an error pasted below. I can't figure this out, so I would be very thankful if someone could help me with this.

As the error message suggests, you should contact Code Aster team (the forum) with the relevant files: mesh, comm file, possibly export file.

It is likely a bug so they'd be happy to receive a report.

OK thanks.
I will raport this to Code Aster if I get the user ID someday.
