Analyzing Events

You can analyze the events.

Before you begin: To have a model to work with, do the following:
  1. From the Signal Monitor, right-click any signal or node and select Simulation Analysis .
  2. Click the Event Log tab.
    The Event Log tab contains a list of all event points that happened during the simulation, sorted by time, and the number of events for each event point.

    If the option Events during initialization is activated, also those events are displayed at time 0.

    Notes:
    • The window can be minimized, it is then displayed with the icon on the right side of the screen.
    • If no events occurred, the Event Log tab is not displayed.
  3. To see also the minor events, activate Minor Events.

    By default this option is cleared, to let you concentrate on the main events.

    Note: The model Coupled Clutches used in this scenario generates no minor events.

  4. To see the details of the events for a specific time, expand that time node.

    Tips:
    • You can also double-click a time node to expand it.
    • You can use the Alt and Ctrl keys to select several time nodes, and then use Expand Event to expand them.
    • You can expand all time nodes by right-clicking a node or event line and select Expand All.
    • You can collapse all time nodes by right-clicking a node or event line and select Collapse All.

    The following information appears in the columns:
    • The time of an iteration containing one or several events.
    • The number of iterations.
    • The expression that triggered a specific event.
    • The value of the expression after a specific event.
  5. To search a specific event expression, in the Expression filter field, start entering the event expression.
    The filtering is dynamically applied.
  6. To investigate where a certain event expression appears, including the display of other events, do the following:
    1. Search the event, see previous step.
    2. Right-click the event line and select Highlight Expression.
      The expression for the event is highlighted at all times where it appears.
      Important: Only highlights in expanded nodes are displayed.
    3. In the Expression filter field, remove the expression.
      All event expressions are now displayed. The specific event expression is still highlighted.

    Tip: If you want to do this for an event expression that you see without searching, select it and click Expand Event.

    Important: If you close a node, there is no indication on that node if it contains a highlighted error expression. To check, see next step.
  7. At any time, to display the highlighted error expression and at what times it is used, right-click any node or line and click Expand Highlighted.

    The highlight is remembered until you close the event log window.

  8. To display an overview of the events during the integration in a plot, click Plot Event Overview.
    Time events and state events are plotted in the active plot window, or, if no active plot window exists, in a new plot window.
