I am modeling the deformation of a sphere made of rubbery material using static simulation. The simulation stops and advise me to turn the "Large Displacement" option on because the shape of the sphere changes under load, but then when I use the large displacement option, the simulation stops and does not converge. Please help me figure this out. I have also attempted to use non-linear option without any luck. I must mention that I setup the simulation on an assembly of the soft sphere  sandwiched between two steel plates. This is to simulate an actual mechanical stress test. 

Please help me figure this out!

Thanks!
