Preferences dialogue box : "Run" settings

Run time environment

Use single window: This option selects between the single-window and multiple-window run time environments. The former is the most common choice.

Reset sliders on model reset

This controls whether resetting a model to its initial state causes sliders that have been adjusted during the previous run to return to their default positions. The sliders will always return to default positions when re-running the model.

Position of run control and input sliders

When not using the single window run time environment, the initial positions of the run control and slider windows are specified here, in the form xy, x and y specify the desired location of window on the screen, in pixels.

Each of x and y must be preceded by + or - . If x is preceded by +, it specifies the number of pixels between the left edge of the screen and the left edge of window's border; if preceded by - then x specifies the number of pixels between the right edge of the screen and the right edge of window's border. If y is preceded by + then it specifies the number of pixels between the top of the screen and the top of window's border; if y is preceded by - then it specifies the number of pixels between the bottom of window's border and the bottom of the screen. For instance, "+100-100" would place the window a short way in from the bottom left corner. Enter "default" to use Windows built-in placement algorithm.

Numerical value precision

These set the number of significant figures that are used when a floating-point numerical value appears in a popup or a snapshot window. By default it is 12, and setting it greater than this will result in meaningless extra digits being added because the internal representation is double-precision. These displays may be easier to read if you select a lower precision. This setting does not affect data displayed in the I/O tools, which have their own means of setting precision.

Occurrences during execution

There are various things that can pause the model before the execution period set in the run control is complete. Some will always stop it, such as a 'stop()' function executing with a nonzero argument, or a discontinuity when adaptive step size variation is in operation. Others, such as compartment under/overruns, can be set to have that effect in the run control. In any case, a message is displayed in the log tab in the run control; selecting 'dialogue interactions' here causes a more prominent dialogue box to appear as well, requiring an 'OK' before the model can be restarted.
