Block Substitutions for Foundation Library Hydraulic Blocks

The hydraulicToIsothermalLiquid conversion tool replaces hydraulic blocks in your model with the corresponding isothermal liquid blocks. This table lists the Foundation Library > Hydraulic library and the replacement Isothermal Liquid blocks. For information on blocks from the Fluids > Hydraulics (Isothermal) library, see Block Substitutions for Simscape Fluids Hydraulics (Isothermal) Blocks (Simscape Fluids).

Hydraulic Block	Isothermal Liquid Block
Constant Area Hydraulic Orifice	Local Restriction (IL) with these parameter settings: Restriction type — Fixed
Constant Volume Hydraulic Chamber	Constant Volume Chamber (IL)
Fluid Inertia	There is no equivalent block in the Isothermal Liquid library. The conversion tool comments the block out. To preserve the diagram layout, the conversion tool places the commented out block in a subsystem and connects the subsystem ports to bypass the block. The conversion tool also creates a corresponding entry in the Removed Blocks section of the HTML report. For information on how you can model fluid inertia using the Pipe (IL) block, see Pipes.
Hydraulic Cap	There is no equivalent block in the Isothermal Liquid library because you no longer need to terminate unconnected conserving ports in your model. The conversion tool comments the Hydraulic Cap block out, removes the connection line, and sets the Through variable at the port formerly connected to this block to 0. The conversion tool also creates a corresponding entry in the Removed Blocks section of the HTML report. If you used the Hydraulic Cap block to set the initial value for the Pressure variable, consider modifying the initial pressure value in the block formerly connected to the Hydraulic Cap block.
Hydraulic Piston Chamber	There is no equivalent block in the Isothermal Liquid library because you can model fluid compressibility directly in the mechanical converter blocks. The conversion tool comments the Hydraulic Piston Chamber block out and creates a corresponding entry in the Removed Blocks section of the HTML report.
Hydraulic Reference	Reservoir (IL)
Hydraulic Resistive Tube	Pipe (IL)
Infinite Hydraulic Resistance	Infinite Flow Resistance (IL)
Linear Hydraulic Resistance	Laminar Leakage (IL)
Rotational Hydro-Mechanical Converter	Rotational Mechanical Converter (IL)
Translational Hydro-Mechanical Converter	Translational Mechanical Converter (IL)
Variable Area Hydraulic Orifice	Local Restriction (IL) with these parameter settings: Restriction type — Variable
Variable Hydraulic Chamber	There is no equivalent block in the Isothermal Liquid library because you can model fluid compressibility directly in the mechanical converter blocks. The conversion tool comments the Variable Hydraulic Chamber block out and creates a corresponding entry in the Removed Blocks section of the HTML report.
Hydraulic Flow Rate Sensor	Flow Rate Sensor (IL)
Hydraulic Pressure Sensor	Pressure Sensor (IL)
Hydraulic Constant Flow Rate Source	Flow Rate Source (IL) with these parameter settings: Source type — Constant Flow rate type — Volumetric flow rate
Hydraulic Constant Mass Flow Rate Source	Flow Rate Source (IL) with these parameter settings: Source type — Constant Flow rate type — Mass flow rate
Hydraulic Constant Pressure Source	Pressure Source (IL) with these parameter settings: Source type — Constant
Hydraulic Flow Rate Source	Flow Rate Source (IL) with these parameter settings: Source type — Controlled Flow rate type — Volumetric flow rate
Hydraulic Mass Flow Rate Source	Flow Rate Source (IL) with these parameter settings: Source type — Controlled Flow rate type — Mass flow rate
Hydraulic Pressure Source	Pressure Source (IL) with these parameter settings: Source type — Controlled
Custom Hydraulic Fluid	Isothermal Liquid Properties (IL)
