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 !

Wind Tunnel is the extended version of the Wind Tunnel Free app. It adds visualization modes (turbulence, fluid direction), vga output, ability to load and save scenes, share scenes by email, rotate obstacles, adjust friction and viscosity and many more features.

Full feature list include :

• 4 actions : interact with the fluid, draw obstacles (free or straight lines), draw smoke sources, use eraser tool.
• visualization modes : particles (streamlines, streaklines and random), colored smoke (predefined stripes, streamlines and custom), pressure field, speed norm visualization, curl (visualize turbulences), velocity field (visualize speed direction) combined with speed norm or curl.
• Load/save scenes, share scenes by email, import obstacles shapes as png files.
• Rotate/move obstacles, pause simulation with gestures.
• Adjust physical parameters : fluid viscosity, obstacle friction, wind tunnel input speed.
• Predefined scenes : airfoil, cars, rocks, Kármán vortex street…


The Wind Tunnel app lets you create beautiful wind tunnel scenes, play with the fluid and understand physics effects.
Fluid motion is computed by solving Navier-Stokes equations, at high definition (over 50k grid cells on ipad) thanks to optimized code taking the most out of CPU performance.

What's New

Version 1.3.3

- correction of UI glitches
- new simulation parameters to benefit from A9 and 10 CPUs

Ratings and Reviews

Good App BUT...

jdc9999

This is a good app BUT... While it works well and is perhaps accurate for fluid flow AROUND CLOSED SHAPES it does not correctly model fluid flow THROUGH shapes with openings. For example, draw a simple box and put a single small opening on the windward side of the box. The model will show flow entering that simple opening when in reality it cannot because there is no escape path for that fluid/air. Pressure inside the shape will build to prevent fluid entry. This is not mentioned anywhere and it is entirely possible with the tools available to draw scenarios like this and other "through flow" scenarios that I must assume are equally flawed. Please either 1. include this behavior correctly in your physics modeling, 2. prohibit the drawing of through flow scenarios/shapes or 3. warn users and potential buyers of this limitation. Adding this capability would be great for study of architectural natural ventilation scenarios.

Great Application

I would like to say this is the type of applications that can take the iPad into more of an education and engineering role. Would like to see further updates to be able to use the ipad3 resolution and gpu power. It would be nice to be able to have a true drawing program that can use finer detail and more accuracy in the section creation and input. Even a grid reference in a new draw mode option would be nice. All in all it is a really cool program to experiment with and this program offers so many possibilities and directions to take a new direction in a mobile application. Now all we need is a $6.00 FEA program.

uhhh, what?

Lowering my rating because there has not been an update to address some issues. First of all, this app is awesome! Everything about it is great except for one thing... Why are there features and modes in the regular $1.99 app that are not in the $5.99 app? Kinda feel cheated. I originally got the $2 version, then loved it so much i bought the $6 version. Then come to find out that the "Free Mode" in the $2 version is not in the pro version! What? I will change my rating to 5 stars if the dev adds this back to the pro version. Isn't the point of getting a better more expensive version to get all the features plus some? So now if i want the full experience I have to have both apps on my phone and switch back and forth. That's just not ok by me. I wouldn't have bought this version if i would have known that.
