In my model, if Concrete02 is used, it will not converge, and hints:
WARNING - ForceBeamColumn2d::update - failed to get compatible element forces & deformations for element: 6(dW: << 3.45314e-12)
Domain::update - domain failed in update
DisplacementControl::update - model failed to update for new dU
WARNING AcceleratedNewton::solveCurrentStep() -the Integrator failed in update()
StaticAnalysis::analyze() - the Algorithm failed at step: 0 with domain at load factor 2109.51
OpenSees > analyze failed, returned: -3 error flag
However, it works properly if Concrete01 is used. I hope someone can help me and give me some advice. Thank you for your reply and suggestions.

Re: Why can the model only add 3mm displacement?
I have the same problem. Have you found the answer?
