Dynamical System - Interest - Xholon App

This model implements a dynamical system, a savings account with interest. The same model has been previously implemented using Simulink and Vensim, and it demonstrates how to model dynamical systems using Xholon.

Run it:

1. Run the Java application through the Xhn GUI (org.primordion.xholon.app.Xhn.java), and select File --> Open --> dynsys --> Interest --> Interest_xhn.xml.
2. Expand the Controller node in the tree.
3. Press the Start node.
4. If you have JFreeChart installed you should see a chart like the one below showing the Savings Account Balance series over time.

You can edit the number of years of compound interest in Interest_xhn.xml (param name="MaxProcessLoops" value="10"/>)

Change the interest rate or the starting balance in CompositeStructureHierarchy.

Interest is modelled as an active xholon, which acts upon the savings balance, a passive xholon.
