INSFVMomentumDiffusion
This object implements the Laplace form of the viscous stress in the Navier-Stokes momentum equation, e.g.
−∇⋅μ∇v
where μ is the dynamic viscosity, and v is the velocity.
The object also takes a parameter "complete_expansion" which is false by default. If "complete_expansion" is activated, the following complete formulation is used for the momentum viscous stress:
−[∇⋅μ(∇v+(∇v)T)]
commentnote
The term ∇⋅μ(∇v)T=0 for incompressible flow if a constant dynamic viscosity is used.

# Note that for this model (using the wall-distance mixing length for the entire
# pipe) different von Karman constants are optimal for different Reynolds
