Solid length of spring

Hi All, 

I am trying to run a mechanism analysis where a body of approx  20kg  is held by a 2 springs and is free to fall for a 1m dueto gravity. So when the analysis is over the body compresses the spring and bounces back.

In Creo i can only define spring unloaded length , current lenght , and stiffness coef. I want to see after running the simulation would the spring go solid or not. 

Is there an option to define a solid length ? 

Thanks
