Description
******************************************************************** Special introductory price for a limited time ******
**************************************************************
Do you want to see the effect of the Reynolds Number on the vortex shedding, the effect of the angle of attack on the lift and drag of a 2D profile, the flow around 2D geometry you can easily draw or import ?
Or you just prefer to understand the principles of computational fluid dynamics ?
This App. is for you
NUMECA (www.numeca.be), developer of high-end 3D CFD software and ALGORIZK (www.algorizk.com), developer of interactive physical simulation applications have joined forces and knowledge to provide an Application for Education, aiming at providing 2D quantitative results with comparison to experiments, 3D CFD or analytical results.
Numerical technology includes:
- Immersed Boundary Method using discrete forcing approach
- Spalding wall function turbulence model
- Vorticity confinement method switch (on/off) to add artificial turbulence
- 1st or 2nd order Advection scheme
- CPU and GPU acceleration
Key Features include:
- Choose between two modes: interactive mode to draw obstacles or, import mode to import shapes from text files. These files include numerical settings and can also include reference data for comparison (see format description below).
- Pre-processing tools: mesh size adjustment (max. size is function of the screen definition of your smartphone or tablet), wind tunnel input velocity magnitude and angle, fluid viscosity, periodicity top/down & Reynolds number. Tapping twice on the inlet region opens the boundary condition window.
- Adjust numerical parameters : CFL number, iteration number for the Poisson equation solver, artificial turbulence.
- Visualization: physical fields (pressure, velocity magnitude, velocity components, vorticity), particles (streamlines, streak lines and random), colored smoke (predefined stripes, streamlines or streak lines). Regarding the streamline, you can change the number of streamlines pitching the screen on the inlet region.
- Analyse the flow field using the color scale. Touch the screen on the upper and lower limit of the scale to change the color scale (only for pressure and vorticity).
- Post-processing tools: line or point probes are available to plot the field in a graphic. You can plot the averaged or the instantaneous fields as well as the lift and drag. Strouhal number is available using an automatic Fourier decomposition tool. An output file (in VTK format) of your results is available.
- Tapping twice on the Cartesian plot, the color scale or the information box will remove them
- Load/Save your own configuration.
- Predefined cases are available such as circle cylinder Re=3900, square cylinder Re=500, Durham turbine and others.
Latest updates
What's new in version 1.2

- choice of several color maps: tap the color scale, then "choose colormap"
- ability to re-scale geometry with two finger pinch (now you can translate/rotate/rescale with traditional two-finger gestures)
Bug corrections:
- user interface corrections
- erase wall bug

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.

2 ★So i've got an issue! The app wont start, which is really a shame because i would really like to use it! It looks pretty interesting so i would like it if this issue would be fixed. I know it takes time so im okay waiting for it.
5 ★So I saw this a while back but only recently installed it. It appears to be a functional and even useful CFD solver for your phone. I need to explore the inputs some more, but first impression is that this is a well designed tool.
1 ★Fun to mess around with but not terribly useful since Reynold's numbers and inlet velocities are capped at such low values, which makes modeling external flows impractical and causes results for 2D airfoils to be visually misinterpreted and meaningless. Please increase the maximum velocity (by a lot).
4 ★Well done, the app is very usefull but there isnt the possibility to desing a perfect line and oval, it would be very helpfull because fingers isnt enough precise:^)
3 ★there are still some bugs. on samsung galaxy s4, wall eraser still stops the app. i am not satisfied with the high mesh size. it is very slow.
5 ★Best App ever for mobile phones...Well done Team. Please upgrade the app for 3D objects which can be generated by extrusion or tapered or flared extrusion
5 ★The most useful app I have ever had! Totally worth it!
5 ★Unbelievable, money well spent, very very convenient!
1 ★Program constantly freezes on Samsung Galaxy Edge. Menu displays overlap each other. Stream velocities are only allowed up to 0.25 m/sec and stream does not follow wing profiles closely at all even on low profile wings.
5 ★Very fun to play around with. it looks like there was a lot of time and energy put into the game however there is not much to do in it. I think it should be $3 this way more people would purchase the game.
