Dear All,

I have been using the Abaqus CDP model for quite a while to model reinforced concrete beams. Recently, I am trying using the Concrete Smeared Cracking model in RC beam simulation and I found that convergence issues will always occur. However, when I model the same beam with the CDP model, there is no such issue. Would you mind letting me know if you also encounter a similar issue when using the smeared cracking model? If so, could you please suggest what the possible reason would be?

Regards,

Delon
