NodalMaxValueId

Finds the node id with the maximum nodal value across all postprocessors.

This postprocessor performs a reduction across all ranks to compute the maximum, then returns the id of the node with the global maximum.

Example input syntax

In this input file we obtain both the maximum value of variable u using a NodalExtremeValue and the location where it is reached using a NodalMaxValueId.

[Postprocessors]
  [./max_nodal_pps]
    type = NodalExtremeValue
    variable = u
  [../]
  [./max_node_id]
    type = NodalMaxValueId
    variable = u
  [../]
  [./min_nodal_pps]
    type = NodalExtremeValue
    variable = u
    value_type = min

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.

    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.
