Wind tunnel software isn’t one-size-fits-all—what works for a small low-speed tunnel won’t cut it for hypersonic aerospace tests. But every good platform shares core features, and knowing when to customize can save you from buying unnecessary bloat.

Must-have core functions:

· Real-time data visualization: 2D/3D graphs that update as tests run (e.g., pressure contours on a car model).

· Device synchronization: The ability to link probes, scanners, and tunnel controls (fan speed, temperature) so they start/stop together.

· Data logging with metadata: Stores timestamps, operator notes, and tunnel settings (e.g., “Mach 0.8, 25°C”) alongside raw numbers—critical for later analysis.

· Calibration tracking: Alerts you when probes or sensors are due for recalibration.

Custom development is worth it when:

· You have unique hardware (e.g., a custom 7-hole probe with proprietary output). Off-the-shelf software might not read its data format.

· Your tests follow a specific workflow (e.g., “ramp speed from 10 to 50 m/s, hold for 5 minutes, then cool to -10°C”). Custom scripts can automate this, saving hours per test.

· You need to integrate with other tools (e.g., CFD software like ANSYS for comparing simulated vs. real-world data).

How to avoid over-customizing:
Start with a base platform (e.g., LabVIEW, Dewesoft X) and add plugins for unique needs. Building from scratch costs 5–10x more and takes months longer.
