Full Load Rejection

The Pump as Turbine (PAT) model has one unique transient definition: a Full Load Rejection. This option is shown in the Transient tab of the Pump Properties window.

During this event, the PAT is decoupled from its motor at the specified Transient Initiator, and the PAT undergoes decoupling. The PAT then spins with the fluid until it reaches runaway speed.
