ConstantVectorPostprocessor

Populate constant VectorPostprocessorValue directly from input file.

The constant data is specified with a vector names, and a vector of vectors of values for each name. The vectors of values are separated by semicolons.

A constant vector postprocessor is not generally used for output or postprocessing, but more to isolate part of the system using constant inputs. For example, if a subapp communicates with the main app by transferring a vector postprocessor, a ConstantVectorPostprocessor may be used to replace that transfer for debugging or parametric study purposes.

Example input syntax

In this example, two ConstantVectorPostprocessor are used to specify three vectors a b c. They are tied to each vector postprocessor, so the two do not conflict despite their similar name.

[VectorPostprocessors]
  [from_main_vpp]
    type = ConstantVectorPostprocessor
    vector_names = 'a b c'
    value = '1 1 1; 2 2 2; 3 3 3'
    execute_on = initial
    #outputs = none
  []
  [to_main_vpp]
    type = ConstantVectorPostprocessor
    vector_names = 'a b c'
    value = '4 4 4; 5 5 5; 6 6 6'
    #outputs = none

Input Parameters

  • valueVector values this object will have. Leading dimension must be equal to leading dimension of vector_names parameter.

    C++ Type:std::vector<std::vector<double>>

    Controllable:No

    Description:Vector values this object will have. Leading dimension must be equal to leading dimension of vector_names parameter.

Required Parameters

  • contains_complete_historyFalseSet this flag to indicate that the values in all vectors declared by this VPP represent a time history (e.g. with each invocation, new values are added and old values are never removed). This changes the output so that only a single file is output and updated with each invocation

    Default:False

    C++ Type:bool

    Controllable:No

    Description:Set this flag to indicate that the values in all vectors declared by this VPP represent a time history (e.g. with each invocation, new values are added and old values are never removed). This changes the output so that only a single file is output and updated with each invocation

  • 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, MULTIAPP_FIXED_POINT_END, MULTIAPP_FIXED_POINT_BEGIN, FINAL, CUSTOM, ALWAYS.

    Default:TIMESTEP_END

    C++ Type:ExecFlagEnum

    Options:NONE, INITIAL, LINEAR, NONLINEAR, TIMESTEP_END, TIMESTEP_BEGIN, MULTIAPP_FIXED_POINT_END, MULTIAPP_FIXED_POINT_BEGIN, FINAL, CUSTOM, ALWAYS

    Controllable:No

    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, MULTIAPP_FIXED_POINT_END, MULTIAPP_FIXED_POINT_BEGIN, FINAL, CUSTOM, ALWAYS.

  • parallel_typeREPLICATEDSet how the data is represented within the VectorPostprocessor (VPP); 'distributed' indicates that data within the VPP is distributed and no auto communication is performed, this setting will result in parallel output within the CSV output; 'replicated' indicates that the data within the VPP is correct on processor 0, the data will automatically be broadcast to all processors unless the '_auto_broadcast' param is set to false within the validParams function.

    Default:REPLICATED

    C++ Type:MooseEnum

    Options:DISTRIBUTED, REPLICATED

    Controllable:No

    Description:Set how the data is represented within the VectorPostprocessor (VPP); 'distributed' indicates that data within the VPP is distributed and no auto communication is performed, this setting will result in parallel output within the CSV output; 'replicated' indicates that the data within the VPP is correct on processor 0, the data will automatically be broadcast to all processors unless the '_auto_broadcast' param is set to false within the validParams function.

  • prop_getter_suffixAn optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.

    C++ Type:MaterialPropertyName

    Controllable:No

    Description:An optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.

  • vector_namesvalue Names of the column vectors in this object

    Default:value

    C++ Type:std::vector<std::string>

    Controllable:No

    Description:Names of the column vectors in this object

Optional Parameters

  • 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

    Controllable:No

    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).

  • 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:Yes

    Description:Set the enabled status of the MooseObject.

  • execution_order_group0Execution order groups are executed in increasing order (e.g., the lowest number is executed first). Note that negative group numbers may be used to execute groups before the default (0) group. Please refer to the user object documentation for ordering of user object execution within a group.

    Default:0

    C++ Type:int

    Controllable:No

    Description:Execution order groups are executed in increasing order (e.g., the lowest number is executed first). Note that negative group numbers may be used to execute groups before the default (0) group. Please refer to the user object documentation for ordering of user object execution within a group.
