Good night dear all I hope you can help me.
I have a panel with several contact, I am working with non linear simulation (quasi static, applying an specific displacement on spc rb3 node.
My simulation seems converging quite nice but after a while (reaching 500 iterations), then the output panel displays an error of minimum iteration reached.
I increased my number of increments from 100 to 200 and the problem persists. I have the expertnl and cntstb activated also I increased the number of cutbacks and the error stills.
Most of my contacts are having mcohed material, and the parameters seem quite ok.
The simulation (the non converged) reaches up to 2.1 mm displacement, such value is actually the value obtained in the experiental characterization, hence it seems the simulation is ok, but after 2.1 more or less the simulation stops (I know there is a failure there but I would like to simulate a bit more to see how the failure progresses).
In the attached file you will find the case and the out file
Thanks in advance
