A Program to Numerically Explore Systems of Ordinary Differential Equations

The application is implemented as one window with five pages.

You begin your with the equation edit page. The example is known as the Duffing Equation:

The Equation Page

The initial values page is used to define the integration range and initial values for all equations:

The Equation Page

You use the parameters page to specify values for all system parameters:

The Equation Page

In the diagram page you select the diagram type and define the value ranges for both axes:

The Equation Page

The plot items page is used to specify what to plot. Two versions of this page are available: One for phase diagrams (shown below) and one for time diagrams (not shown):

The Equation Page

The diagram is shown in a separate window. Here you see a solution that moves between two attractors:
