Running Your Model
This section describes how you run a model built with Nova's visual interface.
Once you have built a model but before you run it as a simulation, you must first set the clock parameters. The clock settings consist of the following 4 parameters:
- Start The time (in model time) when the simulation starts (this is usually 0).
- End The time (in model time) when the simulation ends.
- Dt The unit of increment (in model time) for updates.
- Integration Method The mathematical algorithm used to update Stocks and Variables.
Nova currently uses an abstract unit of time that represents some model-dependent real time unit (seconds, minutes, hours, days, years).
Dt, the increment, or "delta t", value, is the amount of time that elapses between State updates. For discrete models this is usually 1 (see below), but can be any value (0.1, 0.01, 0.05, 2, 20).
Nova supports 3 different integration methods
