Configuring Runs

Open the Configuration panel by double-clicking Run Control in the Model Overview, or be right-clicking the Run Control. This is where you will set the time horizon of your model, as well as supplying information for the random number generator.

Ventity™ models simulate the evolution and behavior of entities from an initial time to a final time, proceeding in intervals called time slices. The duration of a time slice is called the time step.

 

1. Inital Time and Final Time (Relative Time). Example: compute changes every hour from hour 12 to hour 36. The simulation period is 24 hours, the time step is 1 hour and so values will be computed for each of 24 time slices.

 

2. Calender Time selector. If checked, model can be set to run using Calender Time, in the pictured case, this would launch the model with an inital time of 8/14/2014 and compute changes every hour until it reached its final time at 8/14/2016. This represents a period of 730 days, so if we kept the Time Step of 1 hour, Ventity would calculate values 17,520 times.

 

3. Time Step sets the interval of time between checks in the model's simulated values. In parenthesis you'll see how many time steps the model will compute before reaching its Final Time.

 

4. Unit of Time sets the units of time to be used in the run of the model. In this case, the unit of time is hour(s).

 

5. If you are using the Random Seed function, this is where you choose the seed value for the random number generator. Enter a specific seed value of your choice. The seed value may be any integer between -999,999,999 and 999,999,999.

6. Run Name. This is the name given to each run. The run name can be specified using this field, the top toolbar next to the run run button, or both. Or, if no run name is provided anywhere, Ventity will develop a run name. See Naming Runs for more information.
