Changing the state of a run

Runs are controlled using the Run toolbar. With the exception of the Start All Runs and Stop All Runs buttons (see below), the tools on this tool bar apply to the selected run in the run schedule.

Start the Selected Run

There are two running modes in Visualyse EPFD: Play and Fast Forward.

In Play mode, simulation views are updated after each time step. This allows you to look at the scenario and the CDF graph as they change over time. You can clearly see the dual timestep operation and watch a number of parameters as they evolve (see next sections on the Scenario Window and the CDF Graph Window).

Fast Forward does not update any of the views until the run ends. Fast Forward is much quicker than Play mode and should be used when monitoring of run parameters is not needed.

Single Step Advance

You can advance the selected run by a single time step by clicking the Single Step Advance button on the run toolbar or by pressing the Space Bar.

Start all Runs

All the runs can be started at once and run in parallel by pressing the green start button on the toolbar. This will start all the runs in Fast Forward mode.

Note that running in parallel will result in very long run times for some systems. It is expected that future versions of Visualyse EPFD will include more sophisticated run management, allowing runs to be co-ordinated between different processors.

Stop all Runs

To complement the Start All Runs button, a Stop All Runs button is provided.

Clicking this button will stop each run at its current timestep.

Stopping a Run

To stop the selected run at its current time step, click the stop button on the Run toolbar.

Resetting a Run

A run can be reset to its start position by clicking the Reset button on the Run toolbar. Resetting a run will delete all the statistics collected so far. You should therefore be careful when using this option.
