An Explicit Event node () specifies an event that occurs at predefined times entered in the Event Timings section. When an event occurs, it is possible to specify reinitialization of global states in the Reinitialization section. Right-click an Explicit Event node to add the Reinitialization on Domains, Boundaries, Edges, or Points node.

Write the first time ti an explicit event occurs in the Start of event text field. It is also possible to repeatedly trigger the event by entering the period T in the Period of event field.

The Use consistent initialization check box is selected by default, which implies that the time-dependent solver will correct the dependent variables after reinitialization. If the provided reinitialization values lead to a consistent state, you can clear this check box to obtain a performance gain. See About the Reinitialization Process for more information.

In the table, enter information in the Variable and Expression columns for the global state variables that the event reinitializes to the given expression.
