Singularity problem in a FEA on Catia

Singularity problem in a FEA on Catia

(OP)
Hi guys,
I've followed a tutorial on Catia V5 r21 to model a wing box structure and after perform an FEM analysis still on Catia. Everything seemed to be okay but I keep getting this error (check attached image).

Every time that I run another static case the problem changes to another rib. So it isn't a problem in that particular rib.

I think that is something on the connection between the 1D and the 2D elements, but the tutorial doesn't say anything about this.

Thanks for your time.
