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

[asceduardo]

Right, it is a full transient analysis. In fact, I have created a probe point to verify the motion of the spring's mass. It gives me zero for all instants of time:

In case it helps, these were the paramers set for the non-linear spring and the analysis:

Could you share your simulation file, so that I can understand why in your case the non-linear spring works properly?
