Pipe2010 and Pipe2012 have the ability to animate pipe profiles. The first and last nodes are specified and the rest is done automatically. Tanks and Reservoir Levels, Pump Speeds, Water Flow or Velocity Rates are all animated. For Surge users many surge devices (such as Air Valves and Bladder Tanks) are also animated in detail. Animation speed can be set and can be stopped (and restarted) interactively at any given simulation time period, allowing the user to view and analyze the model's transient activity thoroughly. Animations can be saved as AVI files.
