2 Building Simple Models with SimEvents Software

inappropriate for this particular example model, which is completely event-based and

contains no blocks with continuous states. The application overrides the inappropriate

parameters and alerts you to that fact.

If you want to prevent these warnings when you simulate event-based models in the

future, you need to set the solver type and step size parameters to appropriate values.

To do this, with your model open in the model editor, open Simulation > Configuration

Parameters > Solver. Under the Solver options section, for the Type: parameter select

the Variable-step option in the drop-down list. For the Solver: parameter, select

Discrete in the drop-down list and in the field for the Max step size: parameter, type

inf. Click OK and save your model.

Results of the Simulation

When the simulation runs, the Signal Scope block opens a window containing a plot. The

horizontal axis represents the times at which entities depart from the server, while the

vertical axis represents the total number of entities that have departed from the server.

After an entity departs from the Single Server block, the block updates its output signal

at the #d port. The updated values are reflected in the plot and highlighted with plotting

markers. From the plot, you can make these observations:

• Until T=1, no entities depart from the server. This is because it takes one second for

the server to process the first entity.
