Reply To: Mass-spring system does not move properly when the spring is non-linear

I wish I could!  Your set up is the same as mine.  If you probe the spring force is it zero also?  If you were now to change the spring back to linear the probe would show non-zero displacements?  It's hard to imagine how that could be.  Are there any warnings in the gui or the Solution Information?
