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).

- 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
INSFVVelocityVariable
INSFVVelocityVariable is a finite volume variable. It overrides the default computation of cell gradients because it must account for a modified computation of boundary face values along a fully developed flow boundary. In addition it toggles the two_term_boundary_expansion to true by default, which 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.

# This example demonstrates how the mixing length model can be tuned to match an
# established correlation for pressure drop in a smooth circular pipe.
# The primary input parameters for this example are the system Reynolds number
# and the von Karman constant for the mixing length model. These two parameters
# can be changed here:
Re = 1e5

# Note that for this model (using the wall-distance mixing length for the entire
