Description

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


If you are interested in more options, check out Wind Tunnel, the paid version of this app, with many more 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:
- 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
- Fixed bugs on boundary conditions.


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 ( 23000 grid cells on ipad ) thanks to a well-optimized code taking the most out of CPU performance.

Thank you all for your great comments.

Do a few changes.

This is a cool app but unlike the paid version of wind tunnel, there is an option to change the angle of attack of the shape you draw like an airfoil but this free version doesn’t have that please add an option for changing the angle of the drawn shape

Great app

This is a great app. I'd like to have a bit of control as to where the flow comes from and points at (have more than one incoming direction) or place fans.
Used it to get an idea of wind flow inside and around my home, and around people.

Cool

This is a very easy and is helpful to tell people about when resistance and drag
