Wind Tunnel Free 1.51

Turn your iPad/iPhone into a wind tunnel simulator! Experience the thrill of drawing obstacles and observing the fluid flow around them. With the ability to experiment with different sizes, shapes, and aerodynamic profiles, you can uncover fascinating insights into fluid dynamics.

With just a tap of the blue button, you gain access to a range of application controls. The three segmented controls allow you to choose between various touch actions, visualization modes, and simulation modes.

• Four touch actions: Interact with the fluid, draw walls, insert a smoke probe, or use the eraser tool.
• Four visualization modes: Observe particles, smoke, pressure fields, or velocity fields.
• Two simulation modes: Experience the wind tunnel with adjustable wind speed or enjoy the freedom of the unconstrained wind in free mode.

If you find yourself thirsting for more options, we invite you to explore Wind Tunnel, the paid version of this app. It boasts a multitude of additional features!

New in version 1.5.1:

• Updated for iOS 9.

New in version 1.5:

• Improved retina graphics.
• New simulation engine for dual-core devices.
• iPhone 5 support.
• Other graphic improvements.

New in version 1.3:

• A much more accurate fluid simulation engine.
• Visualization of velocity fields with an intuitive color scheme (black for fluid at rest, blue, red, and yellow for the highest speeds).
• New preset models to explore, including the exciting "swirl" option.
• The ability to change smoke color: simply double tap on the smoke source, located at the top of the screen, in "interact" touch action and "smoke" mode.
• Bug fixes related to boundary conditions.

New in version 1.2:

• Added support for older iPhones and iPod Touch (armv6).
• Minor bug fixes.
• Added models from the "Lite" version.

The fluid motion in this app is computed by solving Navier-Stokes equations using a highly optimized code. As a result, you can enjoy high definition fluid simulations on your device, with up to 23,000 grid cells on iPad. So, why wait? Start exploring the fascinating world of fluid dynamics today!
