Every Ventity model automatically includes a single Model entity called Model. Defined in that entity are four variables:
Initial Time |
The model time at the start of the simulation. |
Final Time |
The model time at which the simulation ends. |
Time |
The time variable for the model. |
Time Step |
The duration of one time slice. The amount by which time advances during each calculation round. |
The values of the four variables are determined by the Run Configuration. Other entities can access these variables through the model entity. So, to use Time in an equation, you would enter "Model.Time". To use Final Time, enter "Model.Final Time."
Collections
Count |
The number of entities in a collection at the beginning of each time slice. (Built-in variable in all collections) |
