Internal error and shutdown while create failure index results

[hew82]

Hi,
the model consists of 2 shells connected with rigid elements.

The model has got symmetry boundaries.

loads and restraints are implemented over rigid beams that are connected with rigid elements to the shells.

The shell elements have different material definitions which are all laminate materials. the materials are oriented.

Solving and creating ply stresses/strains(post processing) works without warnings&errors.

BUT when I try to create Failure Index results, i got the error messages "Runtime Error Program: c:\programs\ideas11\subtab.exe This appl. has requested the Runtime to terminate in an unusual way....."
and
"APLUS Internal programming error 15402 in routine DSADEA"
The errors occur when confirming the last creation step (solution set)
after confirming both messages IDEAS shuts down.

I also tried to create a simple model with 2 plane shells connected with rigids, this one worked without problems.

I know that is a very special problem, but I hope anyone has got an idea what could be the reason for it.
thanks
hew
