N-Body Simulator

Available in :

Description provided by the Developer

N-body particle simulator where the behaviour of the system is driven only by each particle's gravity.
Set up the initial conditions and watch the system evolve.
You can customize the number of particles, the particle color, the simulation speed, the collision policy, the particle mass and much more.

Description from the Market

N-body particle simulator where the behaviour of the system is driven only by each particle's gravity. It is turning more into a physics playground lately though, with the addition of accelcerometer support, elastic collisions and more.
The app has been completely redesigned. Now there is a simulation box from which the particles can't escape. The system is now much more interactive and it performs way better than the previous version. A mid-range device shouldn't have problems with about 70 particles (without trails and collisions).

-Real n-body simulation, pure gravitational interactions between particles.
-Zoom and pan in big simulation area mode.
-Create walls particles can't trespass. Watch them bounce off.
-Allow or not physically realistic elastic collisions or mergers between particles.
-Set particle and background colors.
-Set gravity strength and particle mass.
-Accelerometer support.
-Shoot particles or create repulsive forces using touchscreen.
-Also create repulsive particles.
-Possibility to choose simulation area size, leaving it just the size of your device's screen or making it large.
-Enable or disable the central black hole which exerts a neat attractive force towards the center.
-Enable or disable particle trails (disable to improve performance).
-Modify simulation velocity in real time.

Check out the new LIVE WALLPAPER version, it's free and it's on the market now! It will remain with the old version of the app by now.

Contact me if you have suggestions for new features or found any bugs.

Needs explaination of the buttons

by trashman the 7/29/2011

What were you thinking This was a great program, now it has way too much overhead, I was able to get a steady 20fps with 70 particles, now I get 6fps with 40 particles, WTF.

Continued updates have introduced fun new features.

The new graphics are bad. Please change back!

Fun to experiment with

by Austin the 7/21/2011

The dev actually wants to make a good product and responded quickly when contacted. I definitely recommend n-body to anyone interested in physics.

Nice App, thanks.

Problem fixed. Can't find anything wrong, and works smoothly.
