The Reinitialization on Domains, Reinitialization on Boundaries, Reinitialization on Edges, or Reinitialization on Points node can reinitialize dependent variables defined on domains when an event occurs. Right-click an Explicit Event or Implicit Event node to add this node.

In the table under Variables enter the dependent variables. In the Expression column, enter the corresponding information for each variable as defined on domains, boundaries, edges, or points that the event reinitializes.
