This script creates the popular NACA 4-Series geometries right within Pointwise. While it’s relatively easy to dig up airfoil coordinates online, it’s much easier to have a script that can generate the geometry. The very first script I wrote eventually became AirfoilGenerator.glf, the topic of this article. The process was so repeatable that once I had learned Glyph I immediately began scripting the airfoil meshing process, the first step of which, was to generate the airfoil geometry.
One of the first grids I generated was an O-Grid for an airfoil. It was 2008 when I began as a summer intern at Pointwise.
