I would recommend you to remove that command, it just sets the key to terminate an analysis.



Terminates program execution if the largest nodal DOF solution value (displacement, temperature, etc.) exceeds this limit. Defaults to 1.0E6 for all DOF except MAG and A. Defaults to 1.0E10 for MAG and A.



Look at the contact settings. Something is putting a high force initially if your materials and mesh are fine (I'll take your word here) and your model is properly constrained. It should be coming from contact as you have fairly straightforward boundary conditions. 


So, what contacts are you using?
