Good Night dear all

I am looking for help.

i have a simple model under compression, (non linear analysis), the system converges nice and smooth with an enforced displacement, however i want to add a self contact, (the model enters in contact while is getting compressed).

Here my question arises, how to do self contact? i tried CONSLI, S2S, and i left blank the main entity, but the system never converges.

 

in attached file you will find the FEM model, (is in zip file because the FEM model is around 17 MB)

 

Thanks in advance
