A N-Body simulation.
This repo contains my Bachelor's thesis.
It has three configurations:
- brute: brute force method
- bhtree: tree based method
- parallel: tree based method (parallel)
- Qt 5.
- C++11 onwards
qmake
make
bin/nbody configuration [iterations] [trace]
Input must come in a file format, in which the first line indicates the number of bodies and the second the radius of the universe.
From the third line, each line represents a body, with the parameters as follows:
mass posx posy velx vly
The program reads the input file from the standard input.
10k.txt: 10000 bodies orbiting in an elliptical way.
10k.txt: 20000 bodies orbiting in an elliptical way.
30k.txt: 30000 bodies orbiting in an elliptical way.
asteroids.txt: 1000 asteroids orbiting around a star.
cluster.txt: A 2500 particle cloud.
collapse.txt: A 2500 particle cloud collapses into a galaxy.
dual.txt: Two galaxies orbiting each other.
galaxy.txt: A galaxy moving through space.
merge.txt: Four 1000 particles collapse.
planets.txt: A star system composed by 4 planets.
saturn.txt: Saturn rings.
spiral.txt: A round galaxy becomes a spiral one.
