The «Wind Tunnel»  app is a software for iOS devices, running on iPhones, iPods and iPads. It turns your iPad/iPhone into a wind tunnel simulator !

Draw obstacles and watch the fluid flow around. Experiment with different sizes, shapes, aerodynamic profiles and see what happens !

Tap the blue button to bring application controls. Three segmented controls let you choose between :

• 4 touch actions           :  interact with the fluid, draw walls, insert smoke probe, use eraser tool.

• 4 visualization modes :  particles, smoke, pressure field, velocity field.

• 2 simulation modes     :  wind tunnel (with adjustable wind speed), free mode (with no constrained wind).

New in version 1.3:

- Much more accurate fluid simulation engine.

- Visualization of velocity field, with this color scheme :  black (fluid at rest), blue, red, yellow (highest speed).

- New preset models (try "swirl" !).

- Ability to change smoke color : in "interact" touch action and "smoke" mode,  double tap on the smoke source, at the top of the screen

1. -Fixed bugs on boundary conditions.
