Utilities
R2026bThe Utilities library contains required and commonly used blocks for setting simulation environment, interfacing with Simulink models, and generating custom components on-the-fly.
This page also contains information about command-line workflows for creating models, programmatically adding and removing connections between physical ports, and setting up utilities for working with certain block types.

Featured Examples
Circuit Breaker with Probe Block
Models a circuit breaker using a Simscape Probe block to access the current and voltage within the electrical switch block and another Simscape Probe block to access the voltage across a load.
Cooling Plate with Channels
A discretized cooling plate with cooling channels, divided into six segments: three on the top and three on the bottom. Each cooling plate segment is modeled as a thermal mass, while cooling channels are modeled using the Pipe (TL). The ConductiveHeatTransferArray, a custom component, models thermal conduction between the cooling plate segments.
Variant Leaf Region in Mechanical System
Simulate the displacement of velocity sources and mass for different variant configurations using leaf type Variant Connector blocks. Variant Connector blocks allow you to activate or deactivate a set of components in the network during simulation without having to physically remove the components or exclude them from simulation.
Variant Bounded Region in Electrical Circuit
Simulate the flow of a current in an electrical circuit for different variant configurations using primary and nonprimary type Variant Connector blocks. Variant Connector blocks allow you to activate or deactivate a set of components in the network during simulation without having to physically remove the components or exclude them from simulation.
Variant Connector Block with Simscape Bus Block
Use Variant Connector blocks with the Simscape Bus block.
Mask Workspace Variable in Variant Connector Block
Use a mask workspace variable as a variant control variable in a Variant Connector block.
