Infinite Pneumatic Resistance

Pneumatic element for setting initial pressure and temperature difference between two nodes

Library

None (example custom library)

• 

Description

Note

As of Release R2016b, the Gas block library replaces the Pneumatic library as the recommended way of modeling pneumatic systems. The former Pneumatic library is now included in the product installation as an example custom library. The pneumatic domain definition is still provided with the software, and all the pneumatic blocks in your legacy models continue to work as before. However, these blocks no longer receive full production support and can be removed in a future release.

The Infinite Pneumatic Resistance block represents an infinite resistance, with no gas or heat flow through it. Use this block to set the initial pressure and temperature difference between two pneumatic nodes without affecting model equations.

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

Ports

The block has two pneumatic conserving ports.
