Wind Tunnel 1.21


Category: Entertainment
Price: $1.99 -> Free, Version: 1.21 (iTunes)

Description:

** Special Thanksgiving event: free for a limited time ! **


Turn 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.
• 3 visualization modes :  particles, smoke, pressure field.
• 2 simulation modes     :  wind tunnel (with adjustable wind speed), free mode (with no constrained wind).


New in version 1.1:
- Visualize pressure in the fluid.
- Wind speed control.
- Compute drag and lift.
- Eraser tool.
- Multicolored smoke.
- Improved smoke resolution.

New in version 1.2:
- Added support for older iphones and ipod touch (armv6)
- Minor bug fixes
- Added models of the "Lite" version


Fluid motion is computed by solving Navier-Stokes equations, at high definition ( 19000 grid cells on ipad ) thanks to a well-optimized code taking the most out of CPU performance.

Thank you all for your great comments.

Warning! ****
Our demanding physics engine uses advanced processor features, the app runs best on iPad, iPhone 3GS, iPhone 4 and iPod touch 3rd generation. It will run on older devices but with lower resolution and frame rates !
