Modal superposition transient structural analysis crashes (SIG$SEGV)

Hello all,

I'm trying to perform a modal superposition transient structural analysis of a fairly small model (<50 000nodes). I'm working in workbench 14.5 and my model contains shells, tetrahedrons and beam elements.

The transient analysis uses a pre-constrained modal analysis. I've tested the approach on an even smaller scaled model and it worked. Now for an unexplained reason, everything seams to go just fine but it ends up crashing at what seams to me the very last moment of the solution. Error is: "unexpected error(SIG$SEGV) has occurred. ANSYS unable to recover and terminates".


There is plenty of disk space on my machine and when I monitor the RAM while it is solving, I'm never exceeding ~5Gb (my machine has 8)

Can anyone help me on that? Thanks a lot!

Louis
