Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:Whether to cache cell gradients or re-compute them.
- components1Number of components for an array variable
Default:1
C++ Type:unsigned int

Controllable:No
Description:Number of components for an array variable
- face_interp_methodaverageSwitch that can select between face interpolation methods.
Default:average
C++ Type:MooseEnum
Unit:(no unit assumed)
Controllable:No
Description:Switch that can select between face interpolation methods.
- familyMONOMIALSpecifies the family of FE shape functions to use for this variable.
Default:MONOMIAL
C++ Type:MooseEnum
Unit:(no unit assumed)
Controllable:No
Description:Specifies the family of FE shape functions to use for this variable.
- fvTrueTrue to make this variable a finite volume variable
Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:True to make this variable a finite volume variable
- orderCONSTANTOrder of the FE shape function to use for this variable (additional orders not listed here are allowed, depending on the family).
Default:CONSTANT
C++ Type:MooseEnum
Unit:(no unit assumed)
Controllable:No
Description:Order of the FE shape function to use for this variable (additional orders not listed here are allowed, depending on the family).
- solver_sysnl0If this variable is a solver variable, this is the solver system to which it should be added.
Default:nl0
C++ Type:SolverSystemName
Unit:(no unit assumed)
Controllable:No
Description:If this variable is a solver variable, this is the solver system to which it should be added.
- two_term_boundary_expansionTrueWhether to use a two-term Taylor expansion to calculate boundary face values. If the two-term expansion is used, then the boundary face value depends on the adjoining cell center gradient, which itself depends on the boundary face value. Consequently an implicit solve is used to simultaneously solve for the adjoining cell center gradient and boundary face value(s).
Default:True
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:Whether to use a two-term Taylor expansion to calculate boundary face values. If the two-term expansion is used, then the boundary face value depends on the adjoining cell center gradient, which itself depends on the boundary face value. Consequently an implicit solve is used to simultaneously solve for the adjoining cell center gradient and boundary face value(s).
- use_dualFalseTrue to use dual basis for Lagrange multipliers
Default:False
C++ Type:bool
Unit:(no unit assumed)
Controllable:No
Description:True to use dual basis for Lagrange multipliers
INSFVScalarFieldVariable
INSFVScalarFieldVariable is a finite volume variable that toggles the two_term_boundary_expansion to true by default. This is the parameter that determines whether extrapolated boundary face values are determined from both the boundary cell centroid value and boundary cell centroid gradient or just the boundary cell centroid value.
