Issue:

When running a simulation, the following message is shown:

User-added image
Model separates into 2 independent components
Soft spring was added

 

Causes:

If the model is not stable, the model will separate into components and Inventor will automatically add softs springs to stabilize it.

Solution:

Soft springs help ensure model stability by preventing rigid body motion without significantly affecting the accuracy of the stress and displacement results.
Soft Springs - Detect and Eliminate Rigid Body Modes

Tips: Check the model, for example if there is a small gap, contacts between individual parts..etc
