Hi Paolo.
Convergence issues can be tricky. Can you share the error message you are getting? Also, it looks like you ran the model with a Large deflection aet to OFF. We generally recommend running the model with a large deflection option set to ON. Also, check for Newton-Raphson residuals. The Newton-Raphson Residual data (if requested) will show graphically which areas had the highest force residuals. These areas usually correlate with the phenomena that are preventing the achievement of force equilibrium (convergence).
Thank you,
