Managing model runs

You can save prior model runs so that you can compare the results of one run against another. Once a run is saved, you can load it at any time to view the data from that run.

When you load a saved run, you can choose to load just the generated data for the run, or both the generated data and the parameters (the initial constant values) for the model's entities. Note that parameters do not include initial values that are generated by equations or graphical functions.

By default, the software automatically saves the last two model runs for any model. When you run the model a third time, the data from the first run are overwritten.

You can specify that the software remembers more than two runs. You can also have the software save one or more runs. Unlike remembered runs, saved runs are available until you delete them. They are not automatically overwritten by subsequent runs.

All model run data are saved in a database file (.ISDB) with the same name and in the same location as your model file.

Note: In order to share saved model runs with other model users, you must include the model's .ISDB file with the model file when you share the model. For more information about which files need to be included when sharing models with others, see Distributing models to users.

To manage model runs

1. From the Run menu, choose Data Manager.

   The Data Manager dialog box opens.

2. Use the options in the Data Manager dialog box to manage the runs:

   • To rename a run, click the run's name and type a new name.
   • To change the number of remembered runs, change the value in the Remember data from the last ___ runs box.
   • To save a run, in the "Current run data" or "Recent run data" list click the button to the right of the run that you want to save. The run appears in the "Saved data" list.
   • To load just the data for a saved or remembered run, in the "Recent run data" or "Saved run data" list, click the button to the right of the run that you want to load.
   • To load the data and parameters for a saved or remembered run, in the "Recent run data" or "Saved run data" list, click the button to the right of the run that you want to load.
   • To delete a saved run, in the "Saved run data" list click the button to the right of the run that you want to delete.

3. When you are finished, click OK.

   If you selected to load a recent or saved run, the model displays the data for the run you selected.

   Notes: If you have comparative or locked tables or graphs in your model, the data in the tables and graphs do not change when you load a saved run.
