The Degree of Freedom Re-Initialization node () is identical to the Degree of Freedom Initialization node that initializes degrees of freedom (dependent variables, shape variables, and global states). There is only one extra section for needed for reinitialization after triggered solver events:

Enter the unique tag in the Event tag field that points to the Event node that triggers this reinitialization step.

To add this node, go to Building Blocks. Right-click Components to add a Component node. Then select Degree of Freedom Re-Initialization from the Elements menu.
