1d Beam element Optistruct

Tsherig

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
