Airfoil Design is the ultimate tool for designing and analyzing aircraft wing sections. With advanced numeric methods, custom mesh generation, and real-time aerodynamic analysis, you can create and refine complex airfoil geometries with precision. Our CFD simulation engine accurately solves Euler's equations, providing insights into compressible, non-viscous flows, including shockwave formations. Key Features: - Design Flexibility: Generate and customize airfoil geometries with 4 types: NACA 4-digit, NACA 5-digit, Modified NACA 4-digit, and Modified NACA 5-digit airfoils. - Real-Time Analysis: Adjust airfoil shapes using intuitive sliders and instantly see the impact on aerodynamic coefficients. - Airfoil Import: Easily import existing airfoils from the airfoiltools.com database. - Custom Mesh Generation: Create o-type grid meshes with our built-in generator and export them for use in other applications. - Advanced CFD Simulation: Simulate airflow around your designs with our powerful CFD engine, now featuring touch pan/zoom, streamlines, CP vectors, and second-order solver. Visualize results with the new Coolwarm color map and export them as PDFs. Whether you’re a professional aerospace engineer or a student of aerodynamics, Airfoil Design offers the tools you need to innovate and explore. Download now to start your aerodynamic journey on your iPad or iPhone. Note: The app is continuously being improved, with new features and bug fixes on the way.

See real airflow around a reference car — free, with every feature included. No account, no subscription, no in-app purchase FlatSixDynamics is a wind tunnel you can hold. The air around the silhouette of a rear-engined sports car moves live, frame by frame, right on your device. Change the setup, and watch the air answer. No footage. No fakery. Actual physics. You set it. You see the result. Drop the ride height from stock to track, and watch the floor start to work: the air under the car speeds up, pressure falls, and the body is pulled toward the road. Deploy the rear wing, and watch the wake behind the car close. Push the speed slider from a standstill to four hundred kilometers per hour, and watch the spoiler rise on its own, exactly as it does on the real vehicle. Every setup change comes back as a number. Track stance at two hundred kilometers per hour: watch the drag figure settle against stock, while the downforce reading breathes with the wake behind the car. Not your car's certified figures. But a number you can argue with.
