Required and commonly used blocks for setting simulation environment, interfacing with Simulink^® models, and generating custom components on-the-fly

This library contains required and commonly used blocks for setting simulation environment, interfacing with Simulink models, and generating custom components on-the-fly.

The blocks in the Network Couplers library provide you with starting points for splitting your Simscape™ network into separate smaller networks interfaced to each other through Simulink connections.

Configuring an EV Simulation for Multirate HIL

An electric vehicle model suitable for multirate Hardware-In-the-Loop (HIL) deployment. The example uses the Simscape™ Network Couplers Library to split the model into separate Simulink® subsystems that can be deployed at different sample rates. This allows you to run parts of the system (for example thermal components) with a slower sample time thereby reducing overall computational cost.

Open Model

Variant Leaf Region in Mechanical System

Simulate the displacement of velocity sources and mass by using the leaf type of the Variant Connector block. The leaf Variant Connector block forms a leaf region that allows you to vary the displacement during simulation.

Open Model
