The problem of this is that groovy can impose an inlet profile but cannot take data downstream (this is the main difficulty) and then rescale to the entry. Adding fluctuation is straight forward.

In "Allwmake" types for the three:
postCalc : libo
foamCalcFunctions : libso
functionObjects : libso

Ref{
In User's Guide "Running wmake"
lib : statically linked lib
libso : dynamically linked lib (*.so)
libo : statically linked object file lib (*.o)

There is a post of Tobi's eq-code explanation on viscous stress.

In incompressible flow, beside normal stress (taken out as p*I), the viscous part is only a function of deviate part of grad(U) (or its transpose).

In "SymmTensorI.H"
there are tow functions for deviate part of a tensor as explained by Tobi : dev and dev2
