Code:

#include "udf.h"
#define P_outlet_ID 2

  real flow;  /* defined outside because will be used in multiple DEFINE macros */

DEFINE_ADJUST(adjust, domain)

  /* "Parallelized" Sections */

foamCalcFunctions : libso
functionObjects : libso

Ref{
In User's Guide "Running wmake"
lib : statically linked lib

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

320 //- Return the deviatoric part of a symmetric tensor

Do it interactively: http://openfoamwiki.net/index.php/Contrib/SwiftBlock
Cheat by using snappyHexMesh, as shown in the tutorial "mesh/snappyHexMesh/iglooWithFridges".
Use Plot3D format to design the mesh, then convert with datToFoam and then run blockMesh.
Use OpenFOAM's codeStream and code it directly
