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.

[ControlLogic]
  [T_inlet_fn]
    type = GetFunctionValueControl
    function = T0_fn
  []

  [set_inlet_value]
    type = SetRealValueControl
    parameter = AuxKernels/aux_kernel/value
    value = T_inlet_fn:value
  []
[]

Input Parameters

parameterThe input parameter(s) to control
C++ Type:std::string
Unit:(no unit assumed)
Controllable:No
Description:The input parameter(s) to control
valueThe name of control data to be set into the input parameter.
C++ Type:std::string
Unit:(no unit assumed)
Controllable:No
Description:The name of control data to be set into the input parameter.

Required Parameters

depends_onThe Controls that this control relies upon (i.e. must execute before this one)
C++ Type:std::vector<std::string>
Unit:(no unit assumed)
Controllable:No
Description:The Controls that this control relies upon (i.e. must execute before this one)

Optional Parameters

control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Unit:(no unit assumed)
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:Set the enabled status of the MooseObject.
implicitTrueDetermines whether this object is calculated using an implicit or explicit form
Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form

Advanced Parameters

(contrib/moose/modules/thermal_hydraulics/test/tests/controls/set_real_value_control/test.i)

# This is testing that the values set by SetRealValueControl are used.
# The values of function T0_fn are set into an aux-field `aux`. Then,
# we compute the average value of this field in a postprocessor. It
# should be equal to the value of T0_fn.
