  27 Description
  28     Steady-state solver for incompressible, 1D turbulent flow, typically to
  29     generate boundary layer conditions at an inlet, for use in a simulation.
  30
  31     Boundary layer code to calculate the U, k and epsilon distributions.
  32     Used to create inlet boundary conditions for experimental comparisons
  33     for which U and k have not been measured.
  34     Turbulence model is runtime selectable.
