AXISYMMETRIC | AXI-SYM - Axisymmetric flow

{AXISYMMETRIC | AXI-SYM} yc theta

This keyword allows a two dimensional grid to be run assuming axisymmetric flow. Note that k_max must be 1, and that the .cgd file is unaware that the grid is axisymmetric or 2D; that is determined at WIND run time.

The user-specified values are defined as:

yc Waterline location of rotation axis, in input units (scaled in WIND by XLONG*SCAFAC and offset by YNOSE)
theta Degrees of rotation assumed for metrics. (Changing theta should not affect the solution, but will affect convergence. I like 5 degrees.)

	yc		Waterline location of rotation axis, in input units (scaled in WIND by `XLONG*SCAFAC` and offset by `YNOSE`)
	theta		Degrees of rotation assumed for metrics. (Changing theta should not affect the solution, but will affect convergence. I like 5 degrees.)
