Description
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.
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)

Incredible, simple, mechanics!!! 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. =)

One Small Suggestion 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!

Could give 3star I just don't like the fact u can't control the blobs
