It might be that convergence was easy up to this point, and now much, much smaller steps are needed to show equilibrium as the snap moves around that corner.Try to add Stabilization in the Nonlinear Controls under Analysis Settings.  Also try much smaller elements around each corner.


Another suggestion is to treat this as a dynamic event and simulate this using Transient Structural.


Either way, it is going to take a long time to simulate.
