The main Interface

The main frame of ModelBuilder is very simple. It contain three menus, a toolbar with 3 buttons, and several text editing boxes for the specification on the model.

The menus

The first menu is the file menu. It contains the standard open, save, save as, close and exit options. These are pretty much self-explanatory.

The second menu is the analysis menu. In this menu You will find to options: Uncertainty Analysis Phase plot. The uncertainty analysis option opens the uncertainty analysis windows, for sensitivity and Uncertainty analyses

The third and last is the help menu and it jus contains the entries for this help and the about  message. 

The Toolbar

The toolbar contains three buttons. The first one is the run button, which starts the simulation.

The second button shows a typeset version of the differential equations in the model (this feature requires the latest version of matplotlib).

The third button shows the results of a simulation on a spreadsheet. From there you can select variables to plot separately and save the results to a csv(comma separated values) file.

The Main Frame

The main frame is designed for the easy specification of a model consisting  of a  system of differential equations. This interface will be covered in a later section where the definition of models is explained.
