GOALS Demonstrate the use of Solidworks
Simulation 2012 Non-linear module. Apply a displacement boundary
condition and calculate the reaction load produced by rubber compression.
Show the hydraulic behavior of the silicone rubber , Poisson’s ratio = 0.495

FEA model 500 step displacement equilibrium
iterations. Achieve Stability at each solution step
for the very flexible rubber with nonlinear behavior.
If the solution diverges try a smaller step size.
Considerable compute resources may be required.
