Wind Tunnel -- for iPad App Reviews

This app is amazing and very accurate. Importing Png allows very precise models equation.

I found this apps well developed and it will very helpfull in my classes.

I´m a engineer and this App can be very helpfull to me, have no parameters shown how speed and viscosity I´m using but can you have idea what is happening with the wind and the fluid.

Its a great app and is teaching physics in a simple and easy to play and understanding way. The abilities are great and it helps a lot to understand fluid dynamics. BUT and this is a big but: the import of png does not work, there are no hints about the dimensions the files should have. There is NO export as png only an obscure wtm file that even Graphic Converter cant read. So its only three stars. Make the png import and export working and ill give 5 or 6 or 7 or 8 starts

very helpful to get understanding aerodynamics on several objects. impressive please add background picture import to improve drawing quality. more drawing tools would be helpfull as well.

Great simulation, very fluid (pun intended) on iPhone5. Works great on iPad1 as well. Only drawback is that the screen boundaries are not detected properly, it varies on each machine... Please test and fix, this is essential for creating funnel type barriers that stretch all the way to the borders of the "tunnel" !!

Smoke is not compatible with iOS5 tho...

This app really is awesome, what a great way to understand aero/fluid dynamics. It is a ton of fun and besides the educational aspect it is an great way to kill some time. Instead of paying 10 bucks for board games give this a whirl, you shant be disappointed One thing though, ability to erase propellers without resetting smoke pattern NEEDS to be in the newest update.

First and foremost, one needs to be able to at least add XY coordinates for airfoils. Id like to be able to view Marske 7 activity, among others.

Fun to experiment Thank you

like it a bunch. recommend you hook up with a .png outfit so one doesnt have to use itunes to import.....itunes is so hogans goat. it scrambles my desktop way bad, and loses apps, so you have to re-install at itunes notoriously sloooooow speeds....

This app is amazing! To be able to do flow visualization on an iPhone is very cool! I would like to see a library of NACA airfoils, maybe a way to define shapes using coordinates and formulas

Best CFD simulator on the app market!

Ok, I am a mech engineer and a turbo designer, so I am a bit biased. This app is just outstanding. If you are interested in external fluid flow fun, get the Pro HD version. The price is worth the capability. I have used it to show people simple flow visualizations. Thanks for the app. Can you make one that shows flow through bends so I can show designers why a tight bend is not a good idea?

This is a great looking app! Great start, but not quiet a pro app yet Healthy criticism: Because of the PRO title I hope to see that there is a better way of creating objects. The current draw wall is barbaric at best compared to any real drawing app. Itd be nice to have a way to sketch something out. It would also be nice to be more specific on the parameter section. I think it would be nice to have this app as an actual tool more so than just a play around with wind tunnel. I really like the lift and drag calculations, and would like to see a bit more of these types of features. Great Work!

You guys have really improved this app, I would like some more options for drawing walls, but other than that is perfect.

This app wont appeal to the general app buyer except maybe as a way to create beautiful and colorful dynamic designs. But its much more than that. Its a wonderfully well done wind tunnel simulation tool that allows one to explore wing airfoil design, see what happens when angle of attack becomes too great (creates stall), learn how an airplanes wing flaps increase lift (and drag) at takeoff and landing, see how a spoiler on a race car creates downforce to keep it from lifting off the track, see how air brakes work on plane or car, learn why big rig trucks have those strange devices on top of the cab (to reduce drag), design a house and roof that might survive hurricane force winds, design a bicycle helmet that reduces drag, and MUCH more. Ive played with this for hours (not as much as Angry Birds) and continue to be fascinated with it. The Wright brothers would have killed for this tool. A version of this app will be used in high schools and universities in the near future to teach fluid dynamics and aeronautical design. The user interface is a bit basic but functional, and there should be better tools for creating new models. Some tools are not named well: Draw Wall is simply a freeform drawing brush. Help screens are marginally helpful. But these are minor complaints considering the overall functionality of this incredible app.

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. Isnt 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. Thats just not ok by me. I wouldnt have bought this version if i would have known that.

Please add feature to load background image

One of the best engineering tools ever written for a touch interface. Makes explaining aero über easy. Wow!
