Infinite Hydraulic Resistance

Hydraulic element for setting initial pressure difference between two nodes


Hydraulic Elements

  • Infinite Hydraulic Resistance block


The Infinite Hydraulic Resistance block represents a break in a hydraulic network. There is no fluid flow through the break. However, the fluid properties, specified by the Custom Hydraulic Fluid block connected to the circuit, are the same on both sides of the break. Use this block to set the priority and initial target value to the difference in pressure between port A and port B.

The Variables tab lets you set the priority and initial target value for the Pressure difference variable prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.


The block has two hydraulic conserving ports.
