These videos from the VCAA outline how to get started, and make the most out of this software for VCE Systems Engineering.
Wolfram SystemModeler is a complete physical modeling and simulation tool which uses drag and drop functionality to create sophisticated systems. High fidelity models can be built using pre-defined components. Numerical experiments can then be performed on models to explore system behaviour.
If you are new to SystemModeler you will be surprised at how easy it is to use. Using visual programming techniques, anyone can select pre-defined block elements to explore systems within Engineering, Biology, Chemistry, Economics and much more.
