Some Nice and Free Physics Simulation ProgramsThe Burn Simulation
The burn simulation is an easy
"forest fire simulation".
The reason behind it is to demonstrate that there is a critical
tree density: If there are fewer trees, the flames will not spread,
if there are more trees, the complete forest will turn into ashes.
The main point is that the critical density is a quite narrow value
range; it is nearly impossible to find a density where you can
reliably tell that only half or 30% of the forest will burn down. The ElStat Electrostatic Potential Solver
Imagine there is a 2dim area and you bring some fixed charges (of
finite size) in there. As a consequence, a nonconstant
electrostatic potential will establish. LJFluid: Simple molecular dynamics sim of LennardJones fluid
Molecular dynamics simulation of a fluid using the LennardJones
potential and observing the pair correlation function for different
temperatures. BallImpact: Simple MD sim of lowspeed impact
Lowspeed impact in granular media computed using simple molecular
dynamics simulation of rigid bodies. Things are kept short and simple for
easy understanding. IsingMag: Simple Ising model magnetization simulation
This is a simple but fairly fast simulation of the 2dim Ising model.
There is no fancy graphical user interface but it can be used to plot
e.g. the phase transition. Can be extended easily with own code. The WaTor Simulation
WaTor is a simple predatorprey simulation. The idea goes back to
A. K. Dewdney and it is really fun watching it and tuning
the three parameters while it is running. The Shaney Text Composer
Shaney is a little fun text composer to play with. It reads in some
text files, does some statistics and then produces text of arbitrary
length based on the input.
