Error in STAT_NON_LINE

Teddy · 2022-01-13 14:34:36

Hello dear community,

On the first day of my accession, I already have a question, I have a problem with a shell element that I have previously calculated statically.
If I switch to STAT_NON_LINE, then I get an error that I can't quite follow.

Maybe someone can help me with this?

P.S. I'm a newbie, for tips on literature etc. please contact me

Hi,
CARA_ELEM=elemprop, is missing for your STAT_NON_LINE case.

Hi Mike,

Unfortunately that wasn't the problem, I've changed the analysis so many times now that I forgot the elemprops in the last analysis.

Do you perhaps know what the error message could mean?

Regards, Theo

No i do not. Maybe change to linear elastic material first and then troubleshoot from there.

Hello,

DST elements are not allowed in non-linear analysis.
