Description

The Infinite Flow Resistance (G) block represents a break in a gas network. There is no mass or energy flow through the break. However, the gas properties, specified by the Gas Properties (G) 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 differences in pressure and temperature between port A and port B.

Variables

To set the priority and initial target values for the block variables prior to simulation, use the Initial Targets section in the block dialog box or Property Inspector. For more information, see Set Priority and Initial Target for Block Variables and Initial Conditions for Blocks with Finite Gas Volume.

Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. Nominal values can come from different sources, one of which is the Nominal Values section in the block dialog box or Property Inspector. For more information, see Modify Nominal Values for a Block Variable.
