Short introduction to simulating ApocalypseDynamics with OpenModelica.

The best reference to World3 is the very well written and very easy to read book: "Limits to Growth: The 30‐Year Update".

Authors: Meadows Donella, Jorgen Randers and Denis Meadows. 368p. Chelsea Green, 2004.

Visit www.openmodelica.org to download the Linux version with system dynamics:

Start OpenModelica connection editor (OMEdit). In the File pulldown menu select System Libraries. Select the SystemDynamics library among the system libraries (far down in the list):

Select WorldDynamics, World3 and one of the scenarios, e.g., Scenario2. Click on the right‐arrow (‐>) simulate button (top row) to simulate. To also simulate some other scenario, click on that one and click the simulate button.

To plot, click on one or more of the variables in the right window. You can search for population by typing popul You can simulate several scenarios and plot one or more variable from each simulation in the same diagram. Below from Scenario1, Scenario2, Scenario3.

This plot is from from Scenario2, Scenario3, and Scenario6. The green one ("green growth") was the only sustainable-one as of 2004, that is to say without collapse.
