When you simulate a model, the Sessions pane will open to display simulation of each element in the model. During the simulation, if you ever need to see what diagram a Behavior being simulated has, you can double-click the session in the Sessions pane of the Simulation window. The following figure shows the Sessions pane when Magic Model Analyst is executing the Blackjack sample (Blackjack.mdzip). If you double-click the Behaviors outlined in red, a new tab will open to display the corresponding diagram.
