Mode summary for the H1 example simulation

Objective

Create an initial steady-state condition from which to start the dynamic run.

Observe the dynamic pressure response upon valve closure.

Source

Specify the required flow and pressure.

Specify the boundary pressure.

Pipe

Calculate the discharge pressure in each segment from its upstream pressure and flow.

The flow elements calculate the flow from the pressures in the surrounding wall elements. The wall elements calculate the pressure from the dynamic flow balance, fluid modulus, and pipe elasticity.

Valve

Calculate the outlet pressure.

Calculate the flow from the final pipe segment pressure and valve position.

Sink

Calculate the pressure.

Specify the pressure boundary.
