The models in this zip file can be used as tutorial examples. They are the models used in the Physical Modeling Hands-on Workshop events offered by the MathWorks.
The examples here are models in Simscape, SimMechanics, SimDriveline, SimElectronics, SimHydraulics, and SimPowerSystems that you can build starting with an empty Simulink model. One example focuses on the Simscape language. There are also examples showing you how to use these tools with Simulink Design Optimization, and Stateflow.
