A focused, production-ready meshing project for the NASA Canard Control Missile, one of the most widely used benchmark cases in supersonic computational aerodynamics. This project teaches you how to build a high quality polyhedral mesh entirely through custom console commands in ANSYS Fluent, giving you full control over every meshing decision rather than relying on the default workflow buttons. Every command is explained in detail so you understand not just what to type, but the engineering reasoning behind each decision. A ready-to-use text file with all commands pre-written is included so you can follow along efficiently. This is Part 1 of a two-part series. Part 2 covers the solver setup, simulation, and experimental data validation against NASA wind tunnel data.
