The additional updates have no effect on the statistics generated by the model. However,
the more frequent the updating (i.e., the smaller the time interval entered), the slower the
model run speed. Because of this, it is recommended that the Max Time Btw. Updates
field be set to a high value when only statistics are desired and a low value when smooth
animation is desired for a presentation.
Updating variables at a specific time—The Update action
To update the status of a system discretely, use the Update HiSpeedSim Variables action
in the Actions module. This action sets all of the Arena Packaging variables to their
current values. Note that the action is named “Update HiSpeedSim Variables” rather than
“Update Packaging Variables” to maintain compatibility with previous versions of the
software.
The Simulate module allows you to
specify regular updates of the
Arena Packaging template
variables.
