{AXISYMMETRIC | AXI-SYM} yc θ |
This keyword allows a two-dimensional structured grid to be run assuming axisymmetric flow. Note that kmax must be 1, and that the .cgd file is unaware that the grid is axisymmetric or 2D; that is determined at Wind-US run time.
The user-specified values are defined as:
yc | Waterline location of rotation axis, in input units (scaled in Wind-US by XLONG*SCAFAC and offset by YNOSE) | ||
---|---|---|---|
θ | Degrees of rotation assumed for metrics. (Changing θ should not affect the solution, but will affect convergence. A value of 5 degrees is typical.) |
