Upgrading Hydraulic Models to Use Isothermal Liquid Blocks

Resources for converting models from the hydraulic domain to the isothermal liquid domain

Use the isothermal liquid domain to model hydraulic systems where the working fluid temperature remains constant during simulation. (since R2020a)

The Hydraulic library will be removed in a future release. Use the Isothermal Liquid library instead, which has several advantages over the Hydraulic library. For more information, see Advantages of Using Isothermal Liquid Blocks.
