Could anyone please explain why I would get this error??

Cast Iron tension local NR algorithm does not converge

Thanks in advance.

There is a singularity or a local min / max ambiguity in the Cast Iron constitutive law. The Newton-Raphson algorythm doesn't converge.

thank you. I found the problem. I had an error in defining the tension data of the material model.
Thanks again.
