## Information and Tools

The AdvectiveFluxCalculatorConstantVelocity computes , and that are used in the Kuzmin-Turek (Kuzmin and Turek, 2004) numerical stabilization scheme, when the velocity is constant and uniform over the mesh. is a measure of advective flux between neighbouring nodes, while and quantify how much antidiffusion to allow around the nodes. See A worked example of Kuzmin-Turek stabilization for many explicit details, and numerical diffusion for example of how the Kuzmin-Turek scheme compares with other numerical schemes.

C++ Type:bool

Options:

Description:Set the enabled status of the MooseObject.

• 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).

• 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.
