Log Window

This window is a note pad where the system writes down messages (that users can edit, copy and paste somewhere else). Moreover, during a simulation run the Log window is active, allowing users to control the simulation flow.




Messages
If the model configuration does not specify a Variable to be plotted in a Run Time Plot, then the Log window will write down a single line for each time step terminated (see the example above for the top half window). The lines specify also the number of the simulation exercises to execute, starting from 0, in case multiple simulation asks have been requested (see Simulation Settings). These messages can be suppressed and reinstated with the buttons Fast and Observe respectively.
Users can ask further information reported in the Log window, concerning the state of the stack, that is the single Variable's computations (see the middle of the example window above). This gives information on each single equation computed, the time, and whether is was a normal updating or the computation requested by another equation.
Other messages concern the descriptive statistics produced during a Analysis of Result session (see the last line in the example above).
In general, any error issues a message with details in the Log window.

Simulation Control Buttons
While a simulation is running, users can press one of the buttons in the lowest bar of the window to modify the simulation flow.

Stop
Quit the simulation. Simulation data for the  result analysis are saved up to the last step fully computed. In case users decided to run multiple simulation exercises the remaining simulation runs are not executed.

Fast
Increase the speed of simulation preventing the system from writing messages. In fact, for simple models (with few Variables) spend most of simulation time just writing down the step number computed.
To further increase the simulation speed, minimize (but not destroy!) the Run Time Plot window, if exists.

Observe
Return the system to print the messages on the status of the simulation in case Fast has been previously used.

Debug
Change the simulation in Debug Mode. This means that when a Variable set to be debugged finishes its equation the system interrupts the simulation and start the Debugger, allowing a through check of the status of the model. The button has no effect if no Variable is checked to be debugged.
