ElementL2Norm
buildconstruction:Undocumented Class
The ElementL2Norm has not been documented. The content listed below should be used as a starting point for documenting the class, which includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.
# ElementL2Norm
!syntax description /Postprocessors/ElementL2Norm
## Overview
!! Replace these lines with information regarding the ElementL2Norm object.
## Example Input File Syntax
!! Describe and include an example of how to use the ElementL2Norm object.
!syntax parameters /Postprocessors/ElementL2Norm

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
Options:
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>
Options:
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Options:
Description:Set the enabled status of the MooseObject.
- implicitTrueDetermines whether this object is calculated using an implicit or explicit form

# This test makes sure that when people use an initial condition that accesses _zero
# the code does not crash. The "problem" is that InitialCondition uses _qp which for
# nodal variables loops over nodes, rather then q-points. Thus if people have more
# nodes that q-points (they have to dial a lower q-rule in the Executioner block), the
# code would do an out-of-bounds access and crash.
