BL_INIT nb ixs str igrs [delt] nbli nzone

The BL_INIT keyword signifies the user wishes to initialize a j or k boundary with a laminar or turbulent flat plate boundary layer. The user-specified values are defined as:

	nb		A number from 1 to 4 indicating which boundary to initialize     1    for j = 1 2    for j = jmax 3    for k = 1 4    for k = kmax
	ixs		Integer indicating method for specifying the axial location to start the boundary layer:     1    to specify the i index 2    to specify the x station
	str		i index or x location to start the boundary layer, depending on the value of ixs
	igrs		Integer indicating method for specifying the initial height of the boundary layer:     1    to specify the number of grid points from the wall 2    to specify the thickness 3    to compute thickness from initial x station
	delt		Number of grid points in boundary layer (if igrs = 1), or boundary layer thickness (inches) (if igrs = 2)
	nbli		Integer indicating type of boundary layer and whether to keep constant thickness or grow with x     1    Turbulent profile, growing with x -1    Turbulent profile, constant thickness 2    Laminar profile, growing with x -2    Laminar profile, constant thickness
	nzone		Zone number for initialization     0    All zones > 0    Zone nzone only

A flat plate temperature distribution will also be constructed consistent with the wall temperature boundary condition of either adiabatic or constant temperature wall.

Note: BL_INIT cannot currently do more than one boundary in each zone without over-writing itself.
