====== Tutorial 5 - Connecting the Sub-systems ====== ===== 4/5 ===== **Connecting the sub-systems**\\

  1. Close, or “collapse”, all the [[sub-system|sub-systems]].

  2. Add a [[Connector|Connector]] block in the off-diagonal cell connecting //Agricultural Land// with //Concentrations in Food//.\\

    {{tutorial_5_3.png?400}}\\

  3. Edit the [[Connector|Connector]] and connect the //Conc_Soil// block in the sub-system //AgriLand// to //Conc_Soil - Conc_Food//.\\ \\ {{tutorial_5_4.png}}

    \\

  4. Add a [[Connector|Connector]] block in the off-diagonal cell which connects //Agricultural land// with //Doses//.

  5. Edit the [[Connector|Connector]] and click the **Values** tab. Connect //Conc_Soil-AgriLand// and //Conc_Soil-Doses//.

  6. Add a [[Connector|Connector]] block in the off-diagonal cell which connects //Concentrations in Food// with //Doses//.

  7. Edit the [[Connector|Connector]] and connect //Conc_Crops-Conc_Food// with //Conc_Crops-Doses//.

\\ **Running a simulation** Follow the steps below to run a simulation and see if the connections have been made:

  1. Add both //Conc_Soil-AgriLand// and //Conc_Soil-Doses// to the list of outputs in [[Simulation_Settings|Simulation Settings]].

    {{tutorial_5_5.png}}\\

  2. Run a new simulation and plot these two outputs in the same graph. If //Conc_Soil// (AgriLand) and //Conc_Soil// (Doses) are connected the outputs should be identical.
