Initialization

Initialize Object

This command — accessed from main menu (Plugins > Dynamics) sets the starting position of the selected object to its current position.

Suppose you have switched off the Solver object momentarily so that you can move a rigid body. Having moved the rigid body, you then switch on the solver having forgotten to use the Initialize Object command first. The body will revert to its previous position.

Initialize All Objects

The same applies to this function as described above for Initialize Object, with the exception that here the starting positions of all rigid bodies and soft bodies will be set to their current positions.
