n-body-problem
==============
A java physics simulator for simulating the force of gravity.
Authors: Frederick Ceder and Joakim Uddholm
== Requirements ==
1. Java 1.7 (JRE)
2. Ant
== Building ==
The project was built in the eclipse IDE but can be compiled by ant if
you wish. Either run the `make` command or the `ant` command and it will
compile the project with the correct.
== Running ==
The main programs that might be interesting to you as a tester are:
- 2D visualiser
- the ResultGenerator.
Available runnable scripts:
- 2dvisualiser
- grav_single
- grav_multi
- barneshut_single
- barneshut_multi
== Input parameters ==
./2dvisualiser numBodies numSteps far numThreads collision width height barnes
./grav_single numBodies numSteps far numThreads collision
./grav_multi numBodies numSteps far numThreads collision
./barneshut_single numBodies numSteps far numThreads collision
./barneshut_multi numBodies numSteps far numThreads collision
numBodies and numSteps are mandatory, the rest is optional and will fallback to default values
if no others are entered.
Defaults:
far = 0.5
numThreads = 1 or 2 (Depending on if sequential run or multithreaded)
collision = true
width = 640
height = 480
barnes = false
Definitions:
far := Granularity value in barnes-hut algorithm. Does nothing for other implementations.
numThreads := The number of worker threads used. Does nothing for a sequential run.
collision := Set if collision physics should be activated or not.
width := Width of the window for the GUI.
height := Width of the window for the GUI.
barnes := Set gravitational force to run with a Barnes-Hut implementation.
