%% Tank Fill and Empty Demonstration / Animation
% 
% This demonstration shows how to model the dynamics of liquid in a tank. The
% associated animation provides a graphical display of the tank as it empties and
% refills, based on user-defined tank parameters. The tank empties at the start
% of the simulation and again part way through the simulation. When the simulation
% is stopped, a plot is generated showing the liquid height and the states of the
% two valves.
