Isothermal Liquid Library

Specialized components for modeling fluid networks in the isothermal liquid domain

Isothermal liquid networks do not undergo temperature or viscosity changes due to any processes occurring in or around the network, but can support elevated or reduced temperatures. The fluid properties are a function of pressure. The available blocks include actuator and actuator forces, flow resistances, pumps and pump components with optional pre-parameterization, and a variety of valves with opening and closing dynamics.

In R2020a, the Isothermal Liquid library was introduced as a mass flow rate-based alternative to the Hydraulics (Isothermal) volumetric flow rate-based library. The Isothermal Liquid library introduces block usability improvements. For more information on converting models with Hydraulics (Isothermal) blocks to use Isothermal Liquid blocks, see: Upgrading Hydraulic Models to Use Isothermal Liquid Blocks.

If a specific component does not yet exist in a domain library, you can build your own using the Simscape™ language. For more information, see Creating Custom Components.
