Monitors and Plots in Time Dependent Problems
In time dependent problems the display specifications must be preceded by a display-time declaration statement. The display-time declaration statement may be either of the form
FOR CYCLE = number
in which case the displays will be refreshed every number time steps, or
FOR T = time1 [ timeset ... ]
Where each timeset may be one of the following :
BY delta TO time2
In this case the displays will be refreshed at times specified by the timeset values.
Any number of plot commands can follow a display-time declaration, and the specification will apply to all of them. It is not necessary to give a display-time specification for each plot.
Multiple display time declaration statements can be used. When multiple display time statements are used each applies to all subsequent display commands until a new time declaration is encountered or the MONITORS or PLOTS section ends.
Last Time Step
The the last time step may be referenced using the qualifier endtime :
FOR T = 0 BY 10 TO endtime
In the above example a plot would be generated every ten time units and at the last time step, whatever was defined in the TIME section or whatever was the last time step due to a HALT condition.
