About Dynamical System Simulator

Dynamical System Simulator animates 2D and 3D first-order and second-order systems of differential equations in real time. Watch animated particles move through space leaving a trail in their wake. Great for verifying slope fields, phase portraits, and gaining an intuitive understanding of dynamical systems. Knowledge of differential equations is assumed but the help screen will point you to additional sources of information. The app is pre-loaded with several well known dynamical system configurations that can be selected from the navigation drawer. Parameters for a particular system type can be randomized.


Sample Systems:
• Logistic Population (1D)
• Periodic Harvesting (1D)
• Saddle (2D)
• Source (2D)
• Sink (2D)
• Center (2D)
• Spiral Source (2D)
• Spiral Sink (2D)
• Bifurcations (2D)
• Homoclinic Orbit (2D)
• Spiral Saddle (3D)
• Spiral Sink (3D)
• Lorenz (3D)
• Oscillations (3D)


Mode Settings:
• Matrix (linear) / Expressions (linear or non-linear)
• 2D / 3D
• 1st Order / 2nd Order


Simulation Settings:
• Number of Particles
• Update Rate
• Time Scale (including negative)
• Enable/Disable random initial velocities for particles


View Settings:
• Line Width
• Line Color
• Zooming (with pinch gestures)
• View Rotation (3D only)


In Expressions Mode the following symbols and trigonometric functions can be used:
• x, y, z
• x', y', z' (2nd Order Mode Only)
• t (time)
• sin (sine)
• cos (cosine)
• asin (arcsine)
• acos (arccosine)
• abs (absolute value)

You're the only vector grapher on android, please restate the oscillations as a simple 9x9 matrix: (f=x''+x'+x+y''+y'+y+z''+z'+z), your current notation is way too confusing.

How do I share and could you add it so we can put these as our wallpapers also I love your apps I have every single one

You did it !!!! It was the file that I was looking gor. It's great, also I added a few lines and now I'm able to print the picture out on my old HP plotter 7550A. It works just perfect with my mobile HTC and with the Android emulator on UBUNTU 17.04. You guys rocked the Net. Keep going on. Cherrio Toni

Very nice app. My worry is that I can't extract the graph. Thanks to improve it in that sense.

I really don't get what this app is I know its showing something's molecules and atoms or something but what is this I don't understand. P.s. ingnore my rating sense I don't know what the game is

Wish I had seen this app a long time ago. I think it would be a useful educational tool to help professors draw connections between systems using comparable matrices & graphs. Awesome job to the people responsible for getting this app on the market.

Good but too much maths

Z70%
by Z####:

This app is a fantastic tool. My thought is that since many dynamical systems take place on a torus or a cylinder, the user should be able to specify. All I mean is that the user should be able to state whether a particle flying off to the right will keep going or at some point reappear on the left. That would be a cylinder, for a torus you would have the same property on the top and bottom as well. That would expand the use of this app to angular dynamical systems like the damped driven pendulum. Cheers!

F70%
by F####:

A much much better way to visualize systems than vector fields. My only wishes are that you could see tick marks or some indication of values on each axis, the ability to pan around (e.g. for predator prey model in the first quadrant), and some way to make the system full screen (hide the input bar)

I like when I play something that is hard and a little bit easy

I really dont understand this but it is beautiful !

If you are a math major, professor, or just genuinely curious about math or in particular nonlinear systems then get this app. It's useful, it's fun, and it's educational. SUGGESTION: Have a bifurcation parameter option so you can progress the value of the bifurcation back and forth across a specified interval. Also possibly have the ability to classify fixed points

Please remove the upper bound on particle duration.

But for what???what exactly the uses of this???

I just don't like the fact u can't control the blobs

Wtf ?? Smoke another one

B70%
by B####:

Of every app similar to this....I'm speechless. Just incredible. I suggest that the user can select a particle and that selected particle would bypass the duration of set particles, so the user can see the settings in action. =)

Thanks for this free app, it's really nice!

H70%
by H####:

This is just the thing i was looking for! A light and portable tool right in my hand to use in a jiffy! You guys rock! One prob I just found was that you've used rulers method for integration (for efficiency). But this runs into wrong results fr second order systems. Can you please replace it with RK4 in an update??

I did find very useful in 2d for phase space visualization and in 3d to simulations of central forces ^_^ many thanks!
