+Description
+    Steady-state solver for incompressible, 1D turbulent flow,
+    typically to generate boundary layer conditions at an inlet.
+
+    Boundary layer code to calculate the U, k and epsilon distributions.
+    Used to create inlet boundary conditions for experimental comparisons
+    for which U and k have not been measured.
+    Turbulence model is runtime selectable.

+        \f]
+
+    and momentum equation:

+          + \div \left( \vec{U} \vec{U} \right)
+          - \div \left(\nu \grad \vec{U} \right)
+          = - \grad p
