SetComponentRealValueControl

Control to set a floating point (Real) value of a component parameter with control data boolean

note

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

Example input syntax

In this example, the T0 parameter of the inlet component using the value ControlData of the T_inlet_fn ControlLogic.

Input Parameters

componentThe name of the component to be controlled.
C++ Type:std::string
Controllable:No
Description:The name of the component to be controlled.
parameterThe name of the parameter in the component to be controlled.
C++ Type:std::string
Controllable:No
Description:The name of the parameter in the component to be controlled.
valueThe name of control data to be set in the component.
C++ Type:std::string
Controllable:No
Description:The name of control data to be set in the component.

Required Parameters

depends_onThe Controls that this control relies upon (i.e. must execute before this one)
C++ Type:std::vector<std::string>
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>
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
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
Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form

Advanced Parameters

(moose/modules/thermal_hydraulics/test/tests/controls/set_component_real_value_control/test.i)

# This is testing that the values set by SetComponentRealValueControl are used.
# Function T0_fn prescribes values for T0 at inlet. We output the function
# values via a postprocessor `T_fn` and the inlet values via another
# postprocessor `T_ctrl`. Those two values have to be equal.
