Hello!

In AIM 2020R1, I idealised a bolted connection with spring and set a load value for preload. How will be the preload applied during calculation? If I have a multistep analysis, will be the preload applied during 1st step and after that will it be locked for the remaining steps? Or will be the preload applied in Step "Zero" before the first step? Inside "Simulation Step Manager" I can only activate/suppress/lock "Structural Conditions" such as Support, Force and Bolt Pretension defined on Solid/Line bodies and not on a Spring (which is a "Interface Condition").

AIM's help mentions the following but this is unclear for me: "Springs are typically defined in a stress free or “unloaded” state. This means that no loading conditions exist unless preloading is specified for a 1-D spring, which creates an initial “loaded”
state."
