# ValueJumpIndicator

## Description

ValueJumpIndicator is an error indicator which is appropriate for use with discontinuous finite element discretizations. Similar to the GradientJumpIndicator, it estimates the error on a given element by integrating the jump in the chosen variable's value across the boundary with each of its face neighbors.

## Input Parameters

• variableThe name of the variable that this side indicator applies to

C++ Type:VariableName

Options:

Description:The name of the variable that this side indicator applies to

### Required Parameters

• scale_by_flux_facesFalseWhether or not to scale the error values by the number of flux faces. This attempts to not penalize elements on boundaries for having less neighbors.

Default:False

C++ Type:bool

Options:

Description:Whether or not to scale the error values by the number of flux faces. This attempts to not penalize elements on boundaries for having less neighbors.

• blockThe list of block ids (SubdomainID) that this object will be applied

C++ Type:std::vector

Options:

Description:The list of block ids (SubdomainID) that this object will be applied

### Optional Parameters

• outputsVector of output names were you would like to restrict the output of variables(s) associated with this object

C++ Type:std::vector

Options:

Description:Vector of output names were you would like to restrict the output of variables(s) associated with this object

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

C++ Type:std::vector

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.

• use_displaced_meshFalseWhether 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:False

C++ Type:bool

Options:

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.
