Simscape

Physical System Modeling

With Simscape, you build a model of a system just as you would assemble a physical system. Simscape employs a physical network approach, also referred to as acausal modeling, to model building: Components (blocks) corresponding to physical elements, such as pumps, motors, and op-amps, are joined by lines corresponding to the physical connections that transmit power. This approach lets you describe the physical structure of a system rather than the underlying mathematics. From your model, which closely resembles a schematic, Simscape automatically constructs the differential algebraic equations (DAEs) that characterize the system’s behavior. These equations are integrated with the rest of the Simulink model, and the DAEs are solved directly. The variables for the components in the different physical domains are solved simultaneously, avoiding problems with algebraic loops.
