SimElectronics

Creating Custom Components

You can add components from other physical modeling products to your SimElectronics model. The foundation library in Simscape contains blocks in hydraulic, thermal, magnetic, and other physical domains. Integrating these domains into your SimElectronics model using physical connections helps you model other aspects of your system in a single environment.

Simscape is an object-oriented language based on MATLAB^® that enables you to create your own physical modeling components and libraries. You can define custom components complete with parameterization, physical connections, and equations represented as acausal implicit differential algebraic equations (DAEs). Within your component’s Simscape language file, you can use MATLAB to analyze parameter values, perform preliminary computations, and initialize system variables. The Simulink block and dialog box for your custom component are automatically created from the file.
