SetRealValueControl

Control object that reads a Real value computed by the control logic system and sets it into a specified MOOSE object parameter(s)

note

ControlData is only defined by the thermal hydraulics module control logic.

Example input syntax

In this example, the value parameter of the AuxKernel called aux_kernel using the value ControlData of the T_inlet_fn ControlLogic.
