SUMMARY="Interactive physics simulator"
|
|
DESCRIPTION="Step is an interactive physical simulator. It allows you to explore \
|
|
the physical world through simulations. It works like this: you place some bodies \
|
|
on the scene, add some forces such as gravity or springs, then click Simulate and \
|
|
Step shows you how your scene will evolve according to the laws of physics. You \
|
|
can change every property of the bodies/forces in your experiment (even during \
|
|
simulation) and see how this will change evolution of the experiment. \
|
|
With Step you cannot only learn but feel how physics works!
|
|
|
|
Features:
|
|
* Classical mechanical simulation in two dimensions
|
|
* Particles, springs with damping, gravitational and coulomb forces
|
|
* Rigid bodies
|
|
* Collision detection (currently only discrete) and handling
|
|
* Soft (deformable) bodies simulated as user-editable particles-springs system, sound waves
|
|
* Molecular dynamics (currently using Lennard-Jones potential): gas and liquid, \
|
|
condensation and evaporation, calculation of macroscopic quantities and their variances
|
|
* Units conversion and expression calculation: you can enter something like \"(2 days + \
|
|
3 hours) * 80 km/h\" and it will be accepted as distance value (requires libqalculate)
|
|
* Errors calculation and propagation: you can enter values like \"1.3 ± 0.2\" for any property \
|
|
and errors for all dependent properties will be calculated using statistical formulas
|
|
* Solver error estimation: errors introduced by the solver is calculated and added \
|
|
to user-entered errors
|
|
* Several different solvers: up to 8th order, explicit and implicit, with or without \
|
|
adaptive timestep (most of the solvers require GSL library)
|
|
* Controller tool to easily control properties during simulation (even with \
|
|
custom keyboard shortcuts)
|
|
* Tools to visualize results: graph, meter, tracer
|
|
* Context information for all objects, integrated wikipedia browser
|
|
* Collection of example experiments, more can be downloaded with KNewStuff
|
|
* Integrated tutorials."
