-All examples are based on the following base model, which calculates a dummy plant concentration. You can download the model from [[base_event_model.eco|here]].+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 {{ :base_event_model.eco |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//.
  
-==== Calculating maximum monthly concentration ====+3. Create two compartments //Sky// and //Soil//. Set the initial condition for //Sky// to be **500** (mg) of **Poison**.
  
-Let +4. Add a transfer from //Sky// to //Soil// and set its equation to //"30+sin(time/5)*20+cos(time/3+2)*10"//
  
-==== Killing plants at harvest ====+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:
