Dear all,
I encountered the error message of zero or negative jacobin while modelling 1d beam element in optistruct solver. I tried setting the CHECKEL to NO and as well by remeshing for several times but the error still persist. So anyone here can help me dort out this problem please.
Thank you

Hi
Without having a look in the model is not clear what can be.
But you could start checking, the element orientation nodes/vectors
The mass and inertia moments. If inertia moment values make sense.
I hope this is helpful
Regards
