ADVolumeJunctionAdvectionScalarKernel

Adds advective fluxes for the junction variables for a volume junction

This scalar kernel is used with the VolumeJunction1Phase component. It is used on all of the scalar degrees of freedom associated with the junction model. All of these residuals are computed in ADVolumeJunction1PhaseUserObject and then retrieved in this scalar kernel.

Input Parameters

equation_indexEquation index
C++ Type:unsigned int
Controllable:No
Description:Equation index
variableThe name of the variable that this residual object operates on
C++ Type:NonlinearVariableName
Controllable:No
Description:The name of the variable that this residual object operates on
volume_junction_uoVolume junction user object name
C++ Type:UserObjectName
Controllable:No
Description:Volume junction user object name

Required Parameters

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.
implicitTrueDetermines whether this object is calculated using an implicit or explicit form
Default:True
C++ Type:bool
Controllable:No
Description:Determines whether this object is calculated using an implicit or explicit form
seed0The seed for the master random number generator
Default:0
C++ Type:unsigned int
Controllable:No
Description:The seed for the master random number generator
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
Controllable:No
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.
