  • refab_typeThe type of refabrication. 0 for instantaneous reset of gas, 1 for reset with constant fraction until next refabrication

    C++ Type:std::vector

    Description:The type of refabrication. 0 for instantaneous reset of gas, 1 for reset with constant fraction until next refabrication

  • refab_timeThe time at which the plenum pressure must be reinitialized due to fuel rod refabrication.

    C++ Type:std::vector

    Description:The time at which the plenum pressure must be reinitialized due to fuel rod refabrication.

  • initial_pressure0The initial pressure in the cavity. If not given, a zero initial pressure will be used.

    Default:0

    C++ Type:double

    Description:The initial pressure in the cavity. If not given, a zero initial pressure will be used.

  • refab_volumeThe gas volume at refabrication.

    C++ Type:std::vector

    Description:The gas volume at refabrication.

  • execute_onTIMESTEP_ENDThe list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.

    Default:TIMESTEP_END

    C++ Type:ExecFlagEnum

    Description:The list of flag(s) indicating when this object should be executed, the available options include NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, FINAL, CUSTOM.

  • material_inputThe name of the postprocessor(s) that holds the amount of material injected into the plenum.

    C++ Type:std::vector

    Description:The name of the postprocessor(s) that holds the amount of material injected into the plenum.

Optional Parameters

  • control_tagsAdds user-defined labels for accessing object parameters via control logic.

    C++ Type:std::vector

    Description:Adds user-defined labels for accessing object parameters via control logic.

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Description:Set the enabled status of the MooseObject.

  • allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

    Default:False

    C++ Type:bool

    Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

  • use_displaced_meshTrueWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

    Default:True

    C++ Type:bool

    Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

  • force_preauxFalseForces the GeneralUserObject to be executed in PREAUX

    Default:False

    C++ Type:bool

    Description:Forces the GeneralUserObject to be executed in PREAUX
