Infinite Hydraulic Resistance

Hydraulic element for setting initial pressure difference between two nodes


Hydraulic Elements


The Infinite Hydraulic Resistance block represents an infinite resistance, with no fluid flow through it. Use this block to set the initial pressure difference between two hydraulic nodes without affecting model equations.

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.

Introduced in R2014b
