Tutorial - Time events
This tutorial gives some examples of how to model events that occur at specific time points in a simulation.
Base model
All examples are based on the following base model, which calculates a dummy value we can use for our event experiments. You can download the model from here
1. Edit simulation settings. Set
- Time unit: Days
- Time mode: Time
- Start time: 0.0
- End time: 100.0
- Start date:2000-01-01
- Output options: Produce additional output
- Time points: from start to end with a 1.0 increment
2. Create a material named Poison with the unit mg.
3. Create two compartments Sky and Soil. Set the initial condition for Sky to be 500 (mg) of Poison.
4. Add a transfer from Sky to Soil and set its equation to “30+sin(time/5)*20+cos(time/3+2)*10”
5. Add a transfer from Soil to Sky and set its equation to “30+sin(time/3+2)*10+cos(time/7+3)*20”
*note: make sure that TC is not checked for both transfers
6. When run, the model will output a Sky and Soil concentration like this:
