Based on the MATLAB language, The MathWorks’ Simscape language capability enables textual authoring of physical modeling components, domains, and libraries in the Simulink environment. Simscape extends Simulink for modeling and simulating mechatronic and other multidomain physical systems using a physical network, or acausal modeling, approach. The capability develops reusable models of components and systems for advancing technologies such as fuel cells, wind power systems, and hybrid electric vehicles. The language can be extended by end users and partners to create and share reusable models. Design teams can simulate system, develop control strategies, perform design tradeoffs, and find system performance errors early in the development process. Simscape requires MATLAB and Simulink (each sold separately). Pricing starts at $2,000.
